It is estimated that the dermatology application will contribute significantly the growth of the global stem cell therapy market. This is because stem cell therapy can help decrease the after effects of general treatments for burns such as infections, scars, and adhesion. The increasing number of patients suffering from diabetes and growing cases of trauma surgery will fuel the adoption of stem cell therapy in the dermatology segment.

Global Stem Cell Therapy Market: Overview

Also called regenerative medicine, stem cell therapy encourages the reparative response of damaged, diseased, or dysfunctional tissue via the use of stem cells and their derivatives. Replacing the practice of organ transplantations, stem cell therapies have eliminated the dependence on availability of donors. Bone marrow transplant is perhaps the most commonly employed stem cell therapy.

Osteoarthritis, cerebral palsy, heart failure, multiple sclerosis and even hearing loss could be treated using stem cell therapies. Doctors have successfully performed stem cell transplants that significantly aid patients fight cancers such as leukemia and other blood-related diseases.

Global Stem Cell Therapy Market: Key Trends

The key factors influencing the growth of the global stem cell therapy market are increasing funds in the development of new stem lines, the advent of advanced genomic procedures used in stem cell analysis, and greater emphasis on human embryonic stem cells. As the traditional organ transplantations are associated with limitations such as infection, rejection, and immunosuppression along with high reliance on organ donors, the demand for stem cell therapy is likely to soar. The growing deployment of stem cells in the treatment of wounds and damaged skin, scarring, and grafts is another prominent catalyst of the market.

Cardiac Stem Cells Comments Off on Stem Cell Therapy Market Report | Know the Cutting-Edge Innovations and Future Trends of Market – BioSpace | May 15th, 2021

Researchers used a pig model of heart attacks, which more closely resembles the human heart in size and physiology, and thus has high clinical relevance to human disease.

Researchers used a pig model of heart attacks, which more closely resembles the human heart in size and physiology, and thus has high clinical relevance to human disease.In a large-animal study, researchers have shown that heart attack recovery is aided by injection of heart muscle cells derived from human induced pluripotent stem cell line, or hiPSCs, that overexpress cyclin D2. This research, published in the journal Circulation, used a pig model of heart attacks, which more closely resembles the human heart in size and physiology, and thus has higher clinical relevance to human disease, compared to studies in mice.

An enduring challenge for bioengineering researchers is the failure of the heart to regenerate muscle tissue after a heart attack has killed part of its muscle wall. That dead tissue can strain the surrounding muscle, leading to a lethal heart enlargement.

Heart experts thus have sought to create new tissue applying a patch of heart muscle cells or injecting heart cells to replace damaged muscle. Similarly, they have tried to stimulate division of existing heart muscle cells near the damaged area. This current study, led by researchers at the University of Alabama at Birmingham, shows progress in both goals.

After the experimental heart attack, heart tissue around the infarction site was injected with about 30 million bioengineered human cardiomyocytes that were differentiated from hiPSCs. These cells also overexpress cyclin D2, part of a family of proteins involved in cell division.

Compared to control human cardiomyocytes, the cyclin D2-cardiomyocytes showed enhanced potency to repair the heart. They proliferated after injection, and by four weeks, the hearts had less pathogenic enlargement, reduced size of dead muscle tissue and improved heart function.

Intriguingly, the cyclin D2-cardiomyocytes stimulated not only their own proliferation, but also proliferation of existing heart muscle cells around the infarction site of the pig heart, as well as showing angiogenesis, the development of new blood vessels.

These results suggest that the cyclin D2-cardiomyocyte transplantation may be a potential therapeutic strategy for the repair of infarcted hearts, said study leader Jianyi Jay Zhang, M.D., Ph.D., the chair of Biomedical Engineering, a joint department of the UAB School of Medicine and the UAB School of Engineering.

This ability of the graft cyclin D2-cardiomyocytes to stimulate the proliferation of nearby existing heart cells suggested paracrine signaling, a type of cellular communication where a cell produces a signal that induces changes in nearby cells.

Exosomes small blebs or tiny vesicles that are released by human or animal cells and contain proteins and RNA from the cells that release them are one common form of paracrine signaling.

Zhang and colleagues found that exosomes that they purified from the cyclin D2-cardiomyocyte growth media indeed promoted proliferation of cultured cardiomyocytes. In addition, the treated cardiomyocytes were more resistant to programmed cell death, called apoptosis, induced by low oxygen levels. The exosomes also induced proliferation of various other cell types, including human umbilical vein endothelial cells, human vascular smooth muscle cells and 7-day-old rat cardiomyocytes that have almost undetectable proliferation.

Part of the cargo that exosomes carry are microRNAs, or miRNAs. These short pieces of RNA have the ability to interact with messenger RNA in target cells, and they are robust players of gene regulation in cells. Humans have more than 2,000 miRNAs with different RNA sequences, and these are thought to regulate a third of the genes in the genome.

So, the researchers documented which microRNAs were present in exosomes from the cyclin D2-overexpressing cardiomyocytes and in exosomes from non-overexpressing cardiomyocytes. As expected, they found differences.

Jianyi Jay Zhang, M.D., Ph.D.Together, the exosomes from both types of cells contained 1,072 different miRNAs, and 651 were common to the two exosome groups. However, 332 miRNAs were found only in the cyclin D2-overexpressing cardiomyocytes, and 89 miRNAs were specific for the non-overexpressing cardiomyocytes. In preliminary work of characterizing the effects of specific miRNAs, one particular miRNA from the cyclin D2-overexpressing exosomes was shown to stimulate proliferation when delivered into rat cardiomyocytes.

Thus, as the therapeutic potential of exosomes for improving cardiac function becomes more evident, combining an exosome-mediated delivery of proliferative miRNAs with transplantation of cyclin D2-overexpressing cardiomyocytes, or cell products, could become a new promising strategy for upregulating proliferation of the recipient cardiomyocytes and reducing cardiac fibrosis, Zhang said. Altogether, our data suggest that cardiac cell therapy, involving cardiomyocytes with enhanced proliferation capacity, may become an efficacious future strategy for myocardial repair and prevention of congestive heart failure in patients with acute myocardial infarctions.

UAB Department of Biomedical Engineering co-authors with Zhang, in the study Cyclin D2 overexpression enhances the efficacy of human induced pluripotent stem cell-derived cardiomyocytes for myocardial repair in a swine model of myocardial infarction, are Meng Zhao, Yuji Nakada, Yuhua Wei, Weihua Bian, Anton V. Borovjagin, Yang Zhou and Gregory P. Walcott.

Mice, rats and pigs all share a secret superpower: They can all use their intestines to breathe, and scientists discovered this by pumping oxygen up the animals' butts.

Why run such experiments, you ask? The research team wanted to find a potential alternative to mechanical ventilation, a medical treatment where a machine pushes air into a patient's lungs through the windpipe. Ventilators deliver oxygen to the lungs and help remove carbon dioxide from the blood, but the machines aren't always available.

Early in the COVID-19 pandemic, for example, hospitals faced a severe shortage of ventilators, The New York Times reported. Although doctors can also use a technique called extracorporeal membrane oxygenation (ECMO), where blood is pumped out of the body and reoxygenated with a machine, the procedure carries inherent risks, such as bleeding and blood clots; and it's often less readily available than ventilators, according to Mayo Clinic.

Related: The 10 weirdest medical cases in the animal kingdom

In search of another solution, the study authors drew inspiration from aquatic animals like sea cucumbers and freshwater fish called loaches (Misgumus anguillicandatus), which use their intestines for respiration. It was unclear whether humans and other mammals have similar capabilities, although some scientists attempted to answer that question in the 1950s and 1960s.

"We initially looked at a mouse model system to see if we could deliver oxygen gas intra-anusly," said senior author Dr. Takanori Takebe, a professor at the Tokyo Medical and Dental University and a director at the Center for Stem Cell and Organoid Research and Medicine at Cincinnati Children's Hospital Medical Center.

"Every time we performed experiments, we were quite surprised," Takebe told Live Science.

Without intestinal ventilation, mice placed in a low-oxygen environment survived for only about 11 minutes; with ventilation into their anuses, 75% survived for 50 minutes, thanks to an infusion of oxygen that reached their hearts. The team then tried using oxygenated liquid, rather than gas, in mice, rats and pigs, and they found similarly promising results. The team noted that more work still needs to be done to see if the approach is safe and effective in humans, according to a paper on their findings published May 14 in the journal Med.

"The pandemic has highlighted the need to expand options for ventilation and oxygenation in critical illness, and this niche will persist even as the pandemic subsides," as there will be times when mechanical ventilation is unavailable or inadequate on its own, Dr. Caleb Kelly, a clinical fellow and physician-scientist at Yale School of Medicine, wrote in a commentary of the study. If, after further evaluation, intestinal ventilation eventually becomes common practice in intensive care units, this new study "will be marked by historians as a key scientific contribution," he wrote.

Before starting their experiments in rodents, the team got very familiar with loach guts. The fish take in oxygen mostly through their gills, but occasionally, when exposed to low-oxygen conditions, loaches instead use a portion of their intestines for gas exchange, Takebe said. In fact, in response to the lack of oxygen, the structure of gut tissues near the anus changes such that the density of nearby blood vessels increases and secretion of fluids related to digestion decreases.

These subtle changes allow loaches to "suck up the oxygen more efficiently," Takebe said. In addition, the outermost lining of the loach gut the epithelium is very thin, meaning oxygen can easily permeate the tissue to reach the blood vessels beneath, he added. To simulate this structure in their mouse models, the team thinned out the gut epithelium of the rodents using chemicals and various mechanical procedures.

They then placed the mice under extremely low-oxygen conditions and used a tube to pump oxygen gas up the animals' bums and into their large intestines.

Compared with mice whose gut epithelium had not been thinned, the mice with thin epitheliums survived significantly longer in the experiment with most surviving 50 minutes as compared with about 18 minutes. Again, mice not given any oxygen only survived for about 11 minutes. In addition to surviving longer, the group with thinned-out gut linings showed signs that they were no longer starved for oxygen; they stopped gasping for air or showing signs of cardiac arrest, and the oxygen pressure in their major blood vessels improved.

Although this initial experiment suggested that oxygen could pass through the intestine and into circulation, thinning out the gut epithelium would likely not be feasible in human patients, Takebe said.

Particularly in critically ill patients, "I think additional damage to the gut would be really dangerous, for the treatment perspective," Takebe said. But "over the course of the experiments, we realized that even the intact gut has some, not really efficient, but some capacity to exchange the gas," he noted, meaning there may be a way to introduce oxygen through the gut without first thinning out the tissues.

So in another experiment, rather than using oxygen gas, the team tried perfluorodecalin (PFD), a liquid fluorocarbon that can be infused with a large amount of oxygen. The liquid is already used in people, such as for use in the lungs of infants with severe respiratory distress, the authors noted in their report.

The liquid also acts as a surfactant a substance that reduces surface tension; since a surfactant lines the air sacs of the lungs and helps boost gas exchange in the organ, PFD may fulfill a similar purpose in the intestines, Takebe said.

Much like in the oxygen-gas experiments, the oxygenated PFD rescued mice from the effects of being placed in a low-oxygen chamber, enabling the rodents to meander about their cage more than mice not given the treatment. After just one injection of 0.03 ounces (1 milliliter) of the liquid, the rodents' improvements persisted for about 60 minutes.

"We are not quite sure why this improvement is persisting much longer than the original expectations," Takebe noted, as the authors expected the effects to wear off in just a couple minutes. "But the observation is really reproducible and very robust."

Related: Gasp! 11 surprising facts about the respiratory system

The team then moved on to a pig model of respiratory failure, where they placed pigs on ventilators and only provided a low level of oxygen and then injected PDF into the pigs' posteriors with a long tube. Compared with pigs not given the PFD treatment, pigs given PFD improved in terms of the oxygen saturation of their blood, and the color and warmth returned to their skin. A 13.5 oz (400 ml) infusion sustained these improvements for about 18 to 19 minutes, and the team found that they could give additional doses to the pigs without noticeable side effects.

The team also tested the safety of repeat dosing in rats and found that, while their oxygen levels rose, the animals showed no notable side effects, markers of organ damage or stray PFD lingering in their cells.

Following this success in animal models, Takebe said that his team hopes to start a clinical trial of the treatment in humans sometime next year. They would likely start by testing the safety of the approach in healthy volunteers and beginning to work out what dose levels would be reasonable, he said. However, to make the jump from animals to human patients, the team will need to address a number of critical questions.

For instance, the treatment could potentially stimulate the vagus nerve a long nerve that connects the gut and brain so trial organizers should likely be on the lookout for side effects like falling blood pressure or fainting, Takebe noted. Also, the lower gut contains relatively little oxygen compared with other organs in the body, he added. The community of bacteria and viruses that live in the gut are adapted to these low-oxygen conditions, and a sudden infusion of oxygen might disrupt those microbes, he said.

"The consequence of reversing this so-called 'physiologic hypoxia' is unknown," Kelly noted in his commentary, echoing Takebe's sentiments. In humans, it will be important to determine how many doses of oxygenated liquid could be safely administered into the gut without causing unintended changes to the intestinal environment, he wrote.

In addition, the animal models in the study don't fully reflect what critically ill patients experience during respiratory failure, a condition that often coincides with infection, inflammation and low blood flow, Kelly noted. So there may be additional factors to consider in critically ill patients that weren't relevant in rodents and pigs. And depending on a given patient's condition, they may need a higher or lower dose of PFD all of these fine details will need to be carefully assessed in future trials, Takebe said.

KENILWORTH, N.J.--(BUSINESS WIRE)--Merck & Co. (NYSE: MRK), known as MSD outside the United States and Canada, today announced positive results from the pivotal neoadjuvant/adjuvant Phase 3 KEYNOTE-522 trial investigating KEYTRUDA, Mercks anti-PD-1 therapy, in combination with chemotherapy as pre-operative (neoadjuvant) treatment and then continuing as a single agent (adjuvant) treatment after surgery. KEYNOTE-522 met its dual primary endpoint of event-free survival (EFS) for the treatment of patients with high-risk early-stage triple-negative breast cancer (TNBC). Based on an interim analysis conducted by the independent Data Monitoring Committee (DMC), neoadjuvant KEYTRUDA plus chemotherapy followed by adjuvant KEYTRUDA as monotherapy showed a statistically significant and clinically meaningful improvement in EFS compared with neoadjuvant chemotherapy alone. As previously communicated, KEYNOTE-522 met its other dual primary endpoint of pathological complete response (pCR). The safety profile of KEYTRUDA in this trial was consistent with that observed in previously reported studies; no new safety signals were identified.

KEYTRUDA is the first immunotherapy to show positive results for event-free survival in patients with high-risk early-stage TNBC, a particularly aggressive form of breast cancer, said Dr. Roy Baynes, senior vice president and head of global clinical development, chief medical officer, Merck Research Laboratories. The improvement in pathological complete response rates initially observed following pre-operative treatment was encouraging, and now that we are seeing the data mature after four years to include a statistically significant improvement in event-free survival, we look forward to working with the FDA and other global authorities to bring this new option to patients as quickly as possible. We are grateful to the study participants who are critical to our efforts to advance potential treatment options for patients with TNBC.

An analysis of pCR from KEYNOTE-522 was presented at the European Society for Medical Oncology (ESMO) 2019 Congress and published in the New England Journal of Medicine. Findings showed a statistically significant increase in pCR for KEYTRUDA plus chemotherapy versus chemotherapy alone as neoadjuvant therapy in patients with early-stage TNBC, regardless of PD-L1 status. As previously announced, the company received a Complete Response Letter (CRL) from the FDA in March 2021 regarding Mercks supplemental Biologics License Application (sBLA) seeking approval for KEYTRUDA for the treatment of patients with high-risk early-stage TNBC based on these pCR data and early interim EFS findings. The CRL followed the FDAs Oncologic Drugs Advisory Committee meeting that voted 10-0 that a regulatory decision should be deferred until further data were available from KEYNOTE-522.

The KEYTRUDA clinical development program for TNBC encompasses several internal studies and external collaborative trials, including the ongoing studies KEYNOTE-242 and KEYNOTE-355.

Merck has an expansive clinical development program investigating KEYTRUDA in earlier lines of therapy including in neoadjuvant, adjuvant and locally advanced settings, with approximately 20 registrational studies ongoing.

About KEYNOTE-522

KEYNOTE-522 is a Phase 3, randomized, double-blind trial (ClinicalTrials.gov, NCT03036488), evaluating a regimen of neoadjuvant KEYTRUDA in combination with chemotherapy followed by adjuvant KEYTRUDA as monotherapy versus a regimen of neoadjuvant chemotherapy followed by adjuvant placebo. The dual primary endpoints are pCR and EFS. The secondary endpoints include pCR rate using alternative definitions (i.e., no invasive or noninvasive residual cancer in breast or nodes) at the time of definitive surgery, overall survival, EFS in patients whose tumors express PD-L1 (Combined Positive Score [CPS] 1), safety and patient-reported outcomes. The study enrolled 1,174 patients who were randomized 2:1 to receive either:

About Triple-Negative Breast Cancer (TNBC)

Triple-negative breast cancer is an aggressive type of breast cancer that characteristically has a high recurrence rate within the first five years after diagnosis. While some breast cancers may test positive for estrogen receptors, progesterone receptors or overexpression of human epidermal growth factor receptor 2 (HER2), TNBC tests negative for all three. Approximately 15-20% of patients with breast cancer are diagnosed with TNBC. TNBC tends to be more common in women who are younger than 40 years of age, who are African American or who have a BRCA1 mutation.

About KEYTRUDA (pembrolizumab) Injection, 100 mg

KEYTRUDA is an anti-PD-1 therapy that works by increasing the ability of the bodys immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.

Merck has the industrys largest immuno-oncology clinical research program. There are currently more than 1,400 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient's likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.

Selected Important Safety Information for KEYTRUDA

Severe and Fatal Immune-Mediated Adverse Reactions

KEYTRUDA is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death receptor-1 (PD-1) or the programmed death ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, can affect more than one body system simultaneously, and can occur at any time after starting treatment or after discontinuation of treatment. Important immune-mediated adverse reactions listed here may not include all possible severe and fatal immune-mediated adverse reactions.

Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Early identification and management are essential to ensure safe use of antiPD-1/PD-L1 treatments. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.

Withhold or permanently discontinue KEYTRUDA depending on severity of the immune-mediated adverse reaction. In general, if KEYTRUDA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose adverse reactions are not controlled with corticosteroid therapy.

Immune-Mediated Pneumonitis

KEYTRUDA can cause immune-mediated pneumonitis. The incidence is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 3.4% (94/2799) of patients receiving KEYTRUDA, including fatal (0.1%), Grade 4 (0.3%), Grade 3 (0.9%), and Grade 2 (1.3%) reactions. Systemic corticosteroids were required in 67% (63/94) of patients. Pneumonitis led to permanent discontinuation of KEYTRUDA in 1.3% (36) and withholding in 0.9% (26) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Pneumonitis resolved in 59% of the 94 patients.

Pneumonitis occurred in 8% (31/389) of adult patients with cHL receiving KEYTRUDA as a single agent, including Grades 3-4 in 2.3% of patients. Patients received high-dose corticosteroids for a median duration of 10 days (range: 2 days to 53 months). Pneumonitis rates were similar in patients with and without prior thoracic radiation. Pneumonitis led to discontinuation of KEYTRUDA in 5.4% (21) of patients. Of the patients who developed pneumonitis, 42% of these patients interrupted KEYTRUDA, 68% discontinued KEYTRUDA, and 77% had resolution.

Immune-Mediated Colitis

KEYTRUDA can cause immune-mediated colitis, which may present with diarrhea. Cytomegalovirus infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Immune-mediated colitis occurred in 1.7% (48/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (1.1%), and Grade 2 (0.4%) reactions. Systemic corticosteroids were required in 69% (33/48); additional immunosuppressant therapy was required in 4.2% of patients. Colitis led to permanent discontinuation of KEYTRUDA in 0.5% (15) and withholding in 0.5% (13) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 23% had recurrence. Colitis resolved in 85% of the 48 patients.

Hepatotoxicity and Immune-Mediated Hepatitis

KEYTRUDA as a Single Agent

KEYTRUDA can cause immune-mediated hepatitis. Immune-mediated hepatitis occurred in 0.7% (19/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.4%), and Grade 2 (0.1%) reactions. Systemic corticosteroids were required in 68% (13/19) of patients; additional immunosuppressant therapy was required in 11% of patients. Hepatitis led to permanent discontinuation of KEYTRUDA in 0.2% (6) and withholding in 0.3% (9) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, none had recurrence. Hepatitis resolved in 79% of the 19 patients.

KEYTRUDA with Axitinib

KEYTRUDA in combination with axitinib can cause hepatic toxicity. Monitor liver enzymes before initiation of and periodically throughout treatment. Consider monitoring more frequently as compared to when the drugs are administered as single agents. For elevated liver enzymes, interrupt KEYTRUDA and axitinib, and consider administering corticosteroids as needed. With the combination of KEYTRUDA and axitinib, Grades 3 and 4 increased alanine aminotransferase (ALT) (20%) and increased aspartate aminotransferase (AST) (13%) were seen, which was at a higher frequency compared to KEYTRUDA alone. Fifty-nine percent of the patients with increased ALT received systemic corticosteroids. In patients with ALT 3 times upper limit of normal (ULN) (Grades 2-4, n=116), ALT resolved to Grades 0-1 in 94%. Among the 92 patients who were rechallenged with either KEYTRUDA (n=3) or axitinib (n=34) administered as a single agent or with both (n=55), recurrence of ALT 3 times ULN was observed in 1 patient receiving KEYTRUDA, 16 patients receiving axitinib, and 24 patients receiving both. All patients with a recurrence of ALT 3 ULN subsequently recovered from the event.

Immune-Mediated Endocrinopathies

Adrenal Insufficiency

Thyroiditis occurred in 0.6% (16/2799) of patients receiving KEYTRUDA, including Grade 2 (0.3%). None discontinued, but KEYTRUDA was withheld in <0.1% (1) of patients.

Hyperthyroidism occurred in 3.4% (96/2799) of patients receiving KEYTRUDA, including Grade 3 (0.1%) and Grade 2 (0.8%). It led to permanent discontinuation of KEYTRUDA in <0.1% (2) and withholding in 0.3% (7) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement. Hypothyroidism occurred in 8% (237/2799) of patients receiving KEYTRUDA, including Grade 3 (0.1%) and Grade 2 (6.2%). It led to permanent discontinuation of KEYTRUDA in <0.1% (1) and withholding in 0.5% (14) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement. The majority of patients with hypothyroidism required long-term thyroid hormone replacement. The incidence of new or worsening hypothyroidism was higher in 1185 patients with HNSCC, occurring in 16% of patients receiving KEYTRUDA as a single agent or in combination with platinum and FU, including Grade 3 (0.3%) hypothyroidism. The incidence of new or worsening hypothyroidism was higher in 389 adult patients with cHL (17%) receiving KEYTRUDA as a single agent, including Grade 1 (6.2%) and Grade 2 (10.8%) hypothyroidism.

Type 1 Diabetes Mellitus (DM), Which Can Present With Diabetic Ketoacidosis

Monitor patients for hyperglycemia or other signs and symptoms of diabetes. Initiate treatment with insulin as clinically indicated. Withhold KEYTRUDA depending on severity. Type 1 DM occurred in 0.2% (6/2799) of patients receiving KEYTRUDA. It led to permanent discontinuation in <0.1% (1) and withholding of KEYTRUDA in <0.1% (1). All patients who were withheld reinitiated KEYTRUDA after symptom improvement.

Immune-Mediated Nephritis With Renal Dysfunction

Immune-mediated nephritis occurred in 0.3% (9/2799) of patients receiving KEYTRUDA, including Grade 4 (<0.1%), Grade 3 (0.1%), and Grade 2 (0.1%) reactions. Systemic corticosteroids were required in 89% (8/9) of patients. Nephritis led to permanent discontinuation of KEYTRUDA in 0.1% (3) and withholding in 0.1% (3) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, none had recurrence. Nephritis resolved in 56% of the 9 patients.

Immune-Mediated Dermatologic Adverse Reactions

KEYTRUDA can cause immune-mediated rash or dermatitis. Exfoliative dermatitis, including Stevens-Johnson syndrome, drug rash with eosinophilia and systemic symptoms, and toxic epidermal necrolysis, has occurred with antiPD-1/PD-L1 treatments. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate nonexfoliative rashes. Withhold or permanently discontinue KEYTRUDA depending on severity. Immune-mediated dermatologic adverse reactions occurred in 1.4% (38/2799) of patients receiving KEYTRUDA, including Grade 3 (1%) and Grade 2 (0.1%) reactions. Systemic corticosteroids were required in 40% (15/38) of patients. These reactions led to permanent discontinuation in 0.1% (2) and withholding of KEYTRUDA in 0.6% (16) of patients. All patients who were withheld reinitiated KEYTRUDA after symptom improvement; of these, 6% had recurrence. The reactions resolved in 79% of the 38 patients.

Other Immune-Mediated Adverse Reactions

The following clinically significant immune-mediated adverse reactions occurred at an incidence of <1% (unless otherwise noted) in patients who received KEYTRUDA or were reported with the use of other antiPD-1/PD-L1 treatments. Severe or fatal cases have been reported for some of these adverse reactions. Cardiac/Vascular: Myocarditis, pericarditis, vasculitis; Nervous System: Meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barr syndrome, nerve paresis, autoimmune neuropathy; Ocular: Uveitis, iritis and other ocular inflammatory toxicities can occur. Some cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss; Gastrointestinal: Pancreatitis, to include increases in serum amylase and lipase levels, gastritis, duodenitis; Musculoskeletal and Connective Tissue: Myositis/polymyositis rhabdomyolysis (and associated sequelae, including renal failure), arthritis (1.5%), polymyalgia rheumatica; Endocrine: Hypoparathyroidism; Hematologic/Immune: Hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection.

Infusion-Related Reactions

KEYTRUDA can cause severe or life-threatening infusion-related reactions, including hypersensitivity and anaphylaxis, which have been reported in 0.2% of 2799 patients receiving KEYTRUDA. Monitor for signs and symptoms of infusion-related reactions. Interrupt or slow the rate of infusion for Grade 1 or Grade 2 reactions. For Grade 3 or Grade 4 reactions, stop infusion and permanently discontinue KEYTRUDA.

Complications of Allogeneic Hematopoietic Stem Cell Transplantation (HSCT)

Fatal and other serious complications can occur in patients who receive allogeneic HSCT before or after antiPD-1/PD-L1 treatment. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute and chronic GVHD, hepatic veno-occlusive disease after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between antiPD-1/PD-L1 treatment and allogeneic HSCT. Follow patients closely for evidence of these complications and intervene promptly. Consider the benefit vs risks of using antiPD-1/PD-L1 treatments prior to or after an allogeneic HSCT.

Increased Mortality in Patients With Multiple Myeloma

In trials in patients with multiple myeloma, the addition of KEYTRUDA to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of these patients with an antiPD-1/PD-L1 treatment in this combination is not recommended outside of controlled trials.

Embryofetal Toxicity

Based on its mechanism of action, KEYTRUDA can cause fetal harm when administered to a pregnant woman. Advise women of this potential risk. In females of reproductive potential, verify pregnancy status prior to initiating KEYTRUDA and advise them to use effective contraception during treatment and for 4 months after the last dose.

Adverse Reactions

In KEYNOTE-006, KEYTRUDA was discontinued due to adverse reactions in 9% of 555 patients with advanced melanoma; adverse reactions leading to permanent discontinuation in more than one patient were colitis (1.4%), autoimmune hepatitis (0.7%), allergic reaction (0.4%), polyneuropathy (0.4%), and cardiac failure (0.4%). The most common adverse reactions (20%) with KEYTRUDA were fatigue (28%), diarrhea (26%), rash (24%), and nausea (21%).

In KEYNOTE-054, KEYTRUDA was permanently discontinued due to adverse reactions in 14% of 509 patients; the most common (1%) were pneumonitis (1.4%), colitis (1.2%), and diarrhea (1%). Serious adverse reactions occurred in 25% of patients receiving KEYTRUDA. The most common adverse reaction (20%) with KEYTRUDA was diarrhea (28%).

A groundbreaking new study led by the University of Minnesota, Twin Cities has shown for the first time that lab-created heart valves implanted in young lambs for a year were capable of growth within the recipient.

The valves also showed reduced calcification and improved blood flow function compared to animal-derived valves currently used when tested in the same growing lamb model.

Currently, researchers have not been able to develop a heart valve that can grow and maintain function for paediatric patients. The only accepted options for these children with heart defects are valves made from chemically treated animal tissues that often become dysfunctional due to calcification and require replacement because they dont grow with the child. These children will often need to endure up to five (or more) open heart surgeries until a mechanical valve is implanted in adulthood. This requires them to take blood thinners the rest of their lives.

Minnesota Professor Robert Tranquillo and his colleagues used a hybrid of tissue engineering and regenerative medicine to create the growing heart valves. Over an eight-week period, they used a specialised tissue engineering technique they previously developed to generate vessel-like tubes in the lab from a post-natal donors skin cells. To develop the tubes, the researchers combined the donor sheep skin cells in a gelatine-like material, called fibrin, in the form of a tube and then provided nutrients necessary for cell growth using a bioreactor.

The researchers then used special detergents to wash away all the sheep cells from the tissue-like tubes, leaving behind a cell-free collagenous matrix that does not cause immune reaction when implanted. This means the tubes can be stored and implanted without requiring customised growth using the recipients cells.

The next step was to precisely sew three of these tubes (about 16 mm in diameter) together into a closed ring. The researchers then trimmed them slightly to create leaflets to replicate a structure similar to a heart valve about 19 mm in diameter.

After these initial steps, it looked like a heart valve, but the question then became if it could work like a heart valve and if it could grow, Prof Tranquillo said. Our findings confirmed both.

This second generation of tri-tube valves was implanted into the pulmonary artery of three lambs. After 52 weeks, the valve regenerated as its matrix became populated by cells from the recipient lamb, and the diameter increased from 19 mm to a physiologically normal valve about 25 mm. The researchers also saw a 17 to 34% increase in the length of the valve leaflets as measured from ultrasound images. In addition, researchers showed that the tri-tube valves worked better than current animal-derived valves, with almost none of the calcification or blood clotting that the other valves showed after being implanted in lambs of the same age.

We knew from previous studies that the engineered tubes have the capacity to regenerate and grow in a growing lamb model, but the biggest challenge was how to maintain leaflet function in a growing valved conduit that goes through 40 million cycles in a year, said Zeeshan Syedain, a senior research associate in Prof Tranquillos lab. When we saw how well the valves functioned for an entire year from young lamb to adult sheep, it was very exciting.

This is a huge step forward in paediatric heart research, Tranquillo said. This is the first demonstration that a valve implanted into a large animal model, in our case a lamb, can grow with the animal into adulthood.

If confirmed in humans, the new heart valves could prevent the need for repeated valve replacement surgeries in thousands of children born each year with congenital heart defects. The valves can also be stored for at least six months, which means they could provide surgeons with an off the shelf option for treatment.

The study has now been published in the journal Science Translational Medicine, while the valve-making procedure has been patented and licensed to University of Minnesota start-up company Vascudyne. Prof Tranquillo said the next steps are to implant the tri-tube valve directly into the right ventricle of the heart to emulate the most common surgical repair and then start the process of requesting approval from the US Food and Drug Administration (FDA) for human clinical trials over the next few years.

If we can get these valves approved someday for children, it would have such a big impact on the children who suffer from heart defects and their families who have to deal with the immense stress of multiple surgeries, Prof Tranquillo said. We could potentially reduce the number of surgeries these children would have to endure from five to one. Thats the dream.

Lab-created heart valves grow with the recipient - Lab + Life Scientist

CRISPR is revolutionary. Its also a total brute.

The classic version of the gene editing wunderkind literally slices a gene to bits just to turn it off. Its effective, yes. But its like putting an electrical wire through a paper shredder to turn off a misbehaving light bulb. Once the wires are cut, theres no going back.

Why not add a light switch instead?

This month, a team from the University of California, San Francisco (UCSF) reimagined CRISPR to do just that. Rather than directly acting on genesirrevocably dicing away or swapping genetic lettersthe new CRISPR variant targets the biological machinery that naturally turns genes on or off.

Translation? CRISPR can now flip a light switch to control geneswithout ever touching them directly. It gets better. The new tool, CRISPRoff, can cause a gene to stay silent for hundreds of generations, even when its host cells morph from stem cells into more mature cells, such as neurons. Once the sleeping beauty genes are ready to wake up, a complementary tool, CRISPRon, flips the light switch back on.

This new technology changes the game so now youre basically writing a change [into genes] that is passed down, said author Dr. Luke Gilbert. In some ways we can learn to create a version 2.0 of CRISPR-Cas9 that is safer and just as effective.

The crux is something called epigenetics. Its a whole system of chemicals and proteins that controls whether a gene is turned on or off.

If that sounds confusing, lets start with what genes actually look like inside a cell and how they turn on. By turning on, I mean that genes are made into proteinsthe stuff that builds our physical form, controls our metabolism, and makes us tick along as living, breathing humans.

Genes are embedded inside DNA chains that wrap very tightly around a core proteinkind of like bacon-wrapped asparagus. For genes to turn on, the first step is that they need a bunch of proteins to gently yank the DNA chain off the asparagus, so that the genes are now free-floating inside their cellular space capsule, called the nucleus.

Once that chunk of bacon-y DNA is free, more proteins rush over to grab onto the gene. Theyll then roll down the genes nucleotides (A, T, C, and G) like a lawn mower. Instead of mulch, however, this biological machine spews out a messenger that tells the cell to start making proteinsmRNAs. (Yup, the same stuff that makes some of our Covid-19 vaccines.) mRNA directs our cells protein factory to start production, and voil, that gene is now turned on!

Anything that disrupts this process nukes the genes ability to turn into proteins, essentially shutting it off. Its enormously powerfulbecause one single epigenetic machine can control hundreds or thousands of genes. Its a master light switch for the genome.

The team started with a CRISPR system that has a neutered Cas9. This means that the protein normally involved in cutting a gene, Cas9, can no longer snip DNA, even when tethered to the correct spot by the other component, the guide RNA bloodhound. They then tacked on a protein thats involved in switching off genes to this version of CRISPR.

Heres the clever part: the protein is designed to hijack a natural epigenetic process for switching genes off. Genes are often shut down through a natural process called methylation. Normally, the process is transient and reversible on a gene. CRISPRoff commandeers this process, in turn shutting down any targeted gene but for a far longer period of timewithout physically ripping the gene apart.

Thanks to epigenetics enhancing power, CRISPRoff lets researchers go big. In one experiment targeting over 20,000 genes inside immortalized human kidney cells with CRISPRoff, the team was able to reliably shut those genes off.

Not satisfied with a one-way street, the team next engineered a similar CRISPR variant, with a different epigenetics-related protein, dubbed CRISPRon. In cells inside petri dishes, CRISPRon was able to override CRISPRoff, and in turn, flip the genes back on.

We now have a simple tool that can silence the vast majority of genes, said study author Dr. Jonathan Weissman. We can do this for multiple genes at the same time without any DNA damage and in a way that can be reversed.

Even crazier, the off switch lasted through generations. When the team turned off a gene related to the immune system, it persisted for 15 monthsafter about 450 cellular generations.

The edits also lasted through a fundamental transformation, that is, a cells journey from an induced pluripotent stem cell (iPSC) to a neuron. iPSCs often start as skin cells, and are rejuvenated into stem cells through a chemical bath, when they then take a second voyage to become neurons. This process often wipes away epigenetic changes. But to the authors surprise, CRISPRoffs influence remained through the transformations. In one experiment, the team found that shutting off a gene related to Alzheimers in iPSCs also reduced the amount of subsequently encoded toxic proteins in the resulting neurons.

What we showed is that this is a viable strategy for silencing Tau and preventing that protein from being expressed, said Weissman, highlighting just one way CRISPRoffand controlling the epigenome in generalcan alter medicine.

This isnt the first time someones tried to target the epigenome with CRISPR. The same team previously experimented with another set of CRISPR variants that tried the same thing. The difference between the two is time and stability. With the previous setup, scientists struggled to keep the light switch off for a single generation. The new one has no trouble maintaining any changes through multiple divisionsand transformationsin the genome.

A reliable CRISPR tool for epigenetics is insanely powerful. Although we have drugs that work in similar ways, theyre far less accurate and come with a dose of side effects. For now, however, CRISPRoff and CRISPRon only work in cells in petri dishes, and the next step towards genomic supremacy would be to ensure they work in living beings.

If thats the case, it could change genetic editing forever. From reprogramming biological circuits in synthetic biology to hijacking or reversing ones to prevent disease, epigenetic reprogramming offers a way to do it all without ever touching a gene, nixing the threat of mutationswhile leading to lasting effects through generations.

I think our tool really allows us to begin to study the mechanism of heritability, especially epigenetic heritability, which is a huge question in the biomedical sciences, said study author Dr. James Nuez.

Stem Cell Therapy Market worth $401 million by 2026 - Exclusive Report by MarketsandMarkets - PRNewswire

Bone Marrow Stem Cells Comments Off on Stem Cell Therapy Market worth $401 million by 2026 – Exclusive Report by MarketsandMarkets – PRNewswire | May 3rd, 2021

Lorraine LaRosa faced a seemingly impossible decision.

She knew how fortunate she was to have not one, but three perfect matches for a bone marrow transplant, a procedure used to treat several cancerous and noncancerous diseases, such as leukemia and Hodgkins lymphoma. The statistics for finding a perfect match can be grim. The best odds rest in an immediate family member. Otherwise, a patient must rely on the bone marrow registry and the slim chance of matching with a stranger.

Ms. LaRosa had the benefit of a large family. Out of seven siblings, four were healthy enough to be tested. And three came back as matches: her sisters Jennifer Lappe and Melissa Senatore, who live in Calverton, and her brother Jason Klinge of Southampton.

I was in tears because I didnt know what to do and who was the better choice, Ms. LaRosa said.

A sense of urgency had arrived in early 2020. Ms. LaRosa, 62, who lives in Mattituck, was undergoing frequent blood transfusions due to a lack of platelets and low red blood cells.

Things were getting pretty bad at that point, she said.

She didnt want to put the burden on any of her siblings. She called her doctor to talk through her concerns. The time had come to move forward, so the doctor took the decision out of her hands.

After careful evaluation of all three siblings health and medical histories and considering Ms. LaRosas worsening situation the doctors choice became clear. The donor would be her sister Jennifer.

Ms. Lappe understood her sisters hesitancy to ask forsuch a serious commitment. But there was never a moment of doubt. She had seen her sister struggle for years with her illness and have to endure the uncertainty of misdiagnosis and multiple procedures.

I knew she was scared, Ms. Lappe said. Id be scared with what she had to go through. But shes a lot stronger than I think she thinks she is.

Ms. LaRosa texted her sister with the news that unfortunately she would be the donor.

To me there was never a question, said Ms. Lappe, 60. Ill do whatever you need. Im in a million percent. I said, Im selfish, I love you. I want you to be around forever.

The sisters, who were always so close from a young age and grew up in a tight-knit family, would soon form an unbreakable bond one saving the others life.

Before Ms. LaRosa received an ultimate diagnosis of myelodysplastic syndrome, or MDS, in February 2020, she endured years of joint pain and symptoms that seemed to mystify her doctors. One time when her shoulder hurt, she was told it was a torn rotator cuff, which turned out to be inaccurate. Before that, when she was struggling to walk with swollen feet, a podiatrist said she had a torn Achilles tendon, but she hadnt done anything that seemed to warrant an injury typically seen in athletes. Lupus was also incorrectly diagnosed.

She struggled on a continual journey from one doctor to another.

She ended up in an emergency room on Feb. 27, 2017, and a doctor there noticed that her platelets the smallest blood cells seemed low.

Two months later, a doctor at New York Cancer & Blood Specialists diagnosed large granular leukemia, a rare cancer of white blood cells. As time went on, however, her condition did not improve.

Ms. LaRosas daughter, Taylor, described her mom as a fighter who was always optimistic and never overly concerned about her health issues.

I was more so the worrywart, said Taylor, 29. I kind of forced her to go to all these appointments and all of these doctors chasing all of these kind of vague symptoms. No one could kind of come up with what was going on.

A 2009 Mattituck High School graduate, Taylor works as a physician assistant at Weill Cornell Medical Center in New York City. She connected her mom with Dr. Gail Roboz, who specializes in hematology/oncology, in November 2017. Dr. Roboz became well known as the doctor for Robin Roberts, an anchor of ABCs Good Morning America, who was diagnosed with MDS in 2012.

[Dr. Roboz] kind of took on my case and was monitoring me and was saying my blood didnt really make any sense, Ms. LaRosa said. There were mutations in my blood that werent making sense for the large granular leukemia diagnosis.

Extensive testing revealed that Ms. LaRosa had a predisposition to MDS, a bone barrow disorder and blood cancer that often goes unrecognized and under-diagnosed, according to the MDS Foundation.

Then it was kind of a weird watching and waiting game, Taylor said. I think we all hoped it couldnt turn into this [MDS], but we knew it could.

Low-risk patients who do not receive a bone marrow transplant face an average survival rate of up to six years, according to the MDS Foundation. High-risk patients face as little as five months.

Taylor said she braced herself for the possibility that her mother would need a bone marrow transplant at some point. Each December, her mother would undergo a checkup with her oncologist.

Taylor examined her mothers lab work after the December 2019 appointment and could see the results were abnormal. The family had booked a cruise around Christmastime, so Taylor reached out to her mothers oncologist to see if it would be safe to travel.

Dr. Roboz gave them the OK and said theyd deal with it when they returned.

We went on this cruise and I didnt know anything, Ms. LaRosa said. My husband didnt know anything, but my daughter had all this information. She had some emotional moments on the cruise. Now, looking back, I know why.

Taylor recalled the trip to the Bahamas like something out of a movie, where nothing went wrong.

It was like a perfect trip, she said.

When Ms. LaRosa returned to her doctor for a follow-up, the reality of the situation set in. Dr. Roboz referred her to Dr. Tsiporah Shore, who has expertise in bone marrow transplants, at Weill Cornell Medicine. They met on March 14, 2020.

She basically said we need to do this right away, Ms. LaRosa said. Things were really progressing.

Ms. Lappe could see her sisters health was declining.

Nothing they did was making her better and I know this was something she dreaded doing, she said.

Before determining who would be the match, Ms. Lappe said she underwent the most extensive testing of her life. To find a match, doctors analyze the patients tissue type, specifically the human leukocyte antigen, or HLA, tissue, the proteins found on most cells in the body, according to the nonprofit organization Be the Match.

Finding the match is just the initial step in assuring that the donor is suitable for the transplant and there are no other potential ailments that could be passed on.

Ms. Lappe had assumed her brother Jason would be the pick since she had an autoimmune disease and he did not. When she found out she had been selected, it coincided with the early stage of the pandemic. That added another layer of stress, since Ms. Lappe knew if she came down with the virus, it could upend the entire process.

Other questions loomed over her.

Youre worrying, is my body going to do what it needs to do? Is it going to work? Will her body reject it? she said.

To begin the donation last July, Ms. Lappe received injections to increase her white blood cell count. At the same time, her sister was undergoing radiation and chemotherapy to essentially wipe her immune system clear, eliminating a lifetime of protections that had been built up.

Ms. Lappe said she had been warned shed feel pain in her bones from the shots. When she didnt feel anything after the first shot, she worried it might not be working.

By the third and fourth shot, there was no mistaking the odd sensation.

You have these bone pains, she said. Ive never had that happen.

On the fifth day, the doctors did a blood test as the final determination to begin the donation process.

To read more about bone marrow donation, visit BeTheMatch.org.

The procedure, called peripheral blood stem cell donation, required Ms. Lappe to be connected to a machine for six hours as blood was removed via a port in her chest to separate out the blood-forming cells. The remaining blood circulated back into her body.

At the end of it, one bag of the pinkish liquid that would be used to save her sister had been accumulated.

I said to her afterwards, it was so emotional, Ms. Lappe said, adding that she knew she would feel an overwhelming sense of guilt if the procedure didnt work.

She took a picture of the bag and its label, which read, Donor: Jennifer Lappe and Recipient: Lorraine LaRosa. She texted the picture to her sister and said, Oh, my gosh.

Ms. Lappe finished her donation on a Wednesday and her sister began to receive her bone marrow the next morning, once the doctors had determined they had a sufficient number of stem cells to start the process.

Then the waiting game began.

The day of a transplant is Day Zero. Every day afterward continues an upward count toward engraftment, when the blood-forming cells received during the transplant begin to grow and create healthy blood cells.

I would say those days were the hardest, just waiting, Taylor said. They would draw her labs every morning at 4 a.m. and the results would be back at 6 a.m.

A nurse would write the number on a board, and for several days it remained at zero. To pass the time, Ms. LaRosa would play games like Yahtzee with her husband, Mark, who commuted each day into the city. Taylor would watch Netflix shows like Jane the Virgin with her mom. The days were largely a blur for Ms. LaRosa.

Taylor knew it could take one to two weeks for engraftment to begin. It was Day 11 when they saw the first sign of hope as a nurse wrote .1 on the board, signaling the first sign of growth.

I remember that day being like a huge relief and huge turn, Taylor said.

Ms. LaRosa spent over a month in the hospital for close monitoring as her counts continued to climb. Even after she was released, she had to stay at a nearby hotel for another week because of daily checkups. She set her sights on Day 100, another milestone moment in the recovery.

If you make past Day 100, its a good thing, she said.

Even after a successful procedure with a 100% match, theres never a moment of being entirely in the clear. Ms. LaRosa will continue to be monitored for the rest of her life and setbacks are always possible. Shes faced one setback already, with graft vs. host disease, which can be common after a bone marrow transplant. Shes also endured blood clots.

But the biggest thing is that shes now clear of MDS and feeling better than before the procedure. She still, however, faces residual effects from chemotherapy. Shes often tired.

When she returned home, she mostly stayed inside, unable to venture out with the threat of COVID-19 still hanging over everything. Her immune system was rebuilding from scratch. She remains on a special diet. She cant have plants in the house, which put her at risk of exposure to pathogens that can cause disease. She cant have alcohol.

I said, God, I really want a glass of wine, Ms. LaRosa said with a laugh.

Taylor said there are constant signs of progress. Her mother just recently had a port removed from her chest wall after close to nine months. She received her COVID-19 vaccine. Her hair is growing back.

Shes starting to like the style, Taylor said.

She looks forward to the next steps of returning to normal: going to a movie theater and eating dinner at their favorite restaurant, Grana in Jamesport. When they sit together and toast their wine glasses, Taylor said she knows shell cry. They have always shared a close bond, particularly since Taylor was adopted at around 3 months old after her mother endured years of infertility issues.

Shes been my best friend and my rock for my whole life, Taylor said.

Bone marrow aspiration and trephine biopsy are usually performed on the back of the hipbone, or posterior iliac crest. An aspirate can also be obtained from the sternum (breastbone). For the sternal aspirate, the patient lies on their back, with a pillow under the shoulder to raise the chest. A trephine biopsy should never be performed on the sternum, due to the risk of injury to blood vessels, lungs or the heart.

The need to selectively isolate and concentrate selective cells, such as mononuclear cells, allogeneic cancer cells, T cells and others, is driving the market. Over 30,000 bone marrow transplants occur every year. The explosive growth of stem cells therapies represents the largest growth opportunity for bone marrow processing systems.

Bone Marrow Processing Systems Market Quantitative Market Analysis, Current and Future Trends - Good News Gum

Bone Marrow Stem Cells Comments Off on Bone Marrow Processing Systems Market Quantitative Market Analysis, Current and Future Trends – Good News Gum | May 3rd, 2021

THE FAMILY of a nine-year-old leukaemia patient have been given 10 days to raise funds for life-saving treatment.

Nathaniel Nabenas family are appealing as he "clings on to life" after they were told they have until May 12 to find 201,000 for a stem cell transplant.

2

Without the operation, his cancer will be terminal.

Nathaniel is not entitled to free NHS treatment because he is not a British national.

He flew to the UK to have a 5,000 prosthetic eye fitted privately after losing it to a tumour in his home country Nigeria.

Doctors at Londons Great Ormond Street Hospital, moved by Nathaniels plight, have revealed they have waived their private consultant fees to help.

And Paul OGrady, who presents ITV series Little Heroes at the childrens hospital, has voiced his support.

It was only when he arrived here in November that doctors discovered he had acute myeloid leukaemia, a cancer so aggressive that he could have died within weeks without chemotherapy.

A stem cell match has been found but the family now have to find 201,103.

This money goes to the NHS for the cost of the transplant, treatment and after-care, based on a typical in-patient admission of eight weeks and a three-month follow-up as an outpatient.

2

Nathaniels cancer is in remission after six rounds of chemo but his consultant says it could return at any time.

If they raise enough, then a transplant will go ahead after tests due to take place on May 14.

Parents Ebisidor, a business analyst, and wife Modupe, 38, who are staying with family in Croydon, South London, were initially told the hospital bill could be as much as 825,000.

Ebisidor, 45, told the Mirror: Weve seen a dramatic turnaround from the hopeless situation we were in six months ago and we cant thank Sunday People readers enough.

Its incredible that the doctors are treating him in their private work without charging. They are wonderful. We are so grateful to everyone for giving us hope but at the same time asking people to help Nathaniel cling on to life. We know its a lot to ask.

Professor Ajay Vora, a consultant paediatric haematologist at GOSH, said the superhero fan had been incredibly brave.

But he warned: The cancer could come back at any time and the longer we wait the more likely it will return. Then Nathaniel will only have the option of palliative care.

"The tests we are doing in two weeks will reassure us it hasnt started to come back before we give him the transplant.

Prof Vora added: All the consultants involved in his care are working in a private capacity and have waived their fee because they want to help him.

Our time is not borrowed from the NHS because we are treating Nathaniel in our private service in our time.

Doctors had hoped Nathaniel would be able to have a bone marrow transplant from one of his two sisters Nadia, 11, and Nicole, 21 months. But they were not a match.

Instead, stem cells from a stored umbilical cord will be used to save him.

Doctors will give Nathaniel high doses of chemotherapy to kill off his stem cells and replace them with healthy ones.

Dad Ebisidor said: The faster we can do this transplant the more chance Nathaniel has of survival.

"We dont have this sort of treatment back home. We didnt bring him to the UK sick. He got poorly while he was here. If the operation doesnt work our only option will be to take him to a hospice.

By law, non-UK residents get free emergency care but are charged for operations if they are admitted to hospital.

They pay for treatment at 150% of the NHS national tariff the cost normally incurred for eligible patients.

A Great Ormond Street spokesman said: Nathaniel has responded well to treatment, with our clinical teams working to provide the best care for him including looking at taking advantage of the short window of time for receiving a transplant.
