ORLANDO, Fla.--(BUSINESS WIRE)--Hesperos Inc., pioneers of the Human-on-a-Chip in vitro system, today announced the publication of a new peer-reviewed publication that describes how the companys technology can be used to investigate immune responses following treatment with biological therapeutics for multi-organ systemic diseases, including cancer, infectious diseases and inflammatory disorders. The study was part of a collaboration between Hesperos, Hoffman-La Roche Pharmaceuticals and the University of Central Florida. The manuscript, titled Differential Monocyte Actuation in a Three-Organ Functional Innate Immune System-on-a-Chip, was published today in the prestigious journal Advanced Science. Click here to view a multimedia version of the press release, including media-ready images, downloadable resources, and more.

The immune system plays an important role in coordinating with other organ systems to combat infection, eliminate damaged cells and repair tissue. However, modeling immune response following drug treatment in preclinical studies is challenging due to poor predictability, especially for the innate portion of the system. As the scientific community begins to turn more towards using multi-organ, human-on-a-chip systems as a cost-effective way to increase efficiency and lower toxicity, many of these models lack a systemic immune component.

Hesperos, in collaboration with Hoffmann-La Roche Pharmaceuticals, describe an in vitro, pumpless, three-organ system containing functional human cardiomyocytes, skeletal muscle and hepatocytes in a serum-free medium, along with recirculating human monocyte THP-1 immune cells. Monocytes are a vital immune system cells involved in wound healing, pathogen clearance and activation of the innate immune response, but are also responsible for the cytokine storm found in conditions such as sepsis.

One application where the immune-system-on-a-chip can be immediately useful is for uncovering how severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) directly affects multi-organ systems by activating the cytokine storm from inflammatory macrophages and to support the rapid development of therapeutics. As the global pandemic of COVID-19 continues to grow, this system has the potential to quickly evaluate antiviral and repurposed drugs to help combat this devastating disease, said Michael L. Shuler, Ph.D., Chief Executive Officer of Hesperos.

In the study, the researchers evaluated two different innate immune responses: 1) targeted immune response following tissue-specific damage, which simulates indirect activation of THP-1 cells and, 2) pro-inflammatory immune response following direct activation of immune cells, mimicking acute inflammation and the cytokine storm. Though not reported in this study, Hesperos has also shown that peripheral blood mononuclear cells (PBMCs) and T-cells are sustainable in these multi-organs systems, which would allow some aspects of adaptive immunity to also be modeled.

In the targeted immune response experiments, the cardiotoxic compound amiodarone was used to selectively damage cardiac cells to evaluate how THP-1 immune cells affect the three-organ system. The presence of both amiodarone and THP-1 immune cells led to a more pronounced reduction in cardiac force, conduction velocity and beat frequency compared to amiodarone alone. THP-1 cells were also found to infiltrate the damaged cardiomyocytes and induce significantly increased cytokine IL-6 expression, indicating an M2 macrophage phenotype. No immune-activated damage was reported in the skeletal muscle or liver cells.

The most striking features of our immune-system-on-a-chip is that it emulates different immune reactions for direct tissue-damage and acute inflammation, as well as distinguishes between M1 vs. M2 macrophage phenotypes, said James Hickman, Ph.D., Chief Scientist at Hesperos and Professor at the University of Central Florida.

The study was initially funded by Roche Pharmaceuticals and completed under an NIH grant from National Center for Advancing Translational Sciences (NCATS) Small Business Innovation Research program, which supports studies to advance tissue chip technology toward commercialization.

Tissue chips are a promising technology for accelerating the preclinical timeline and getting treatments to patients more efficiently, said Danilo A. Tagle, Ph.D., associate director for special initiatives at NCATS. Finding improved ways to study immune responses has tremendous implications for drug discovery and the development of more effective personalized medicines in diseases that affect multiple organ systems.

In the pro-inflammatory response experiments, the three-organ system was exposed to lipopolysaccharide (LPS) and interferon gamma (IFN-) to stimulate acute inflammation/cytokine storm and provoke monocyte differentiation and activation. In the absence of THP-1 immune cells, LPS/IFN- treatment had no significant effect on function of the three-organ system. However, with the addition of THP-1 immune cells, LPS/IFN- treatment caused cellular damage to all three-organ components, including THP-1 cell infiltration in liver tissue, and led to significant alterations in cardiac force and beat frequency, as well as skeletal muscle force. Additionally, there was an upregulation of pro-inflammatory cytokines, including TNF-, IL-6 and IL-10, indicating an M1 macrophage phenotype, which is analogous to the cytokine storm found during certain reactions to biologic therapeutics and emulates what occurs during sepsis.

Canine Stem Cell Therapy Market Will Make a Huge Impact in Near Future - Cole of Duty

MedicalResearch.com Interview with:

Charles-de-SM.D., Ph.D.Rio de Janeiro, Brazil

MedicalResearch.com: What is the background for this study?

Response: Our clinical trial was based on our clinical skin observations in areas submitted to a lipotransfer previously, an ordinary practice in plastic surgery. These clinical observations lead us to investigate what will be the key element played in these findings. Our scientific support investigation addressed the Dardick1and Zuk, P2 studies, that demonstrated fibroblastic-like cells in adipose tissue with regenerative ability. Our clinical trial proposal is to investigate the adipose-derived stem cell (ADSC) role in the photoaged skin. The direct endpoint of the study was to assess the histological benefits provided by the subdermal ADSC injection. Mesenchymal stem cells were obtained from lipoaspirates, expanded in vitro, and introduced into the facial skin of 20 patients submitted after three to four months to a face-lifting surgery. In the retrieved skin, immunocytochemical and ultrastructural analysis quantified elastic matrix components, cathepsin-K, metalloprotease MMP-12, and the macrophage M2 markers: CD68, CD206 and heme-oxygenase-1.An overview of the trial steps is described in the infographic.

MedicalResearch.com: What are the main findings?

Response:A full de novo formation of oxytalan and elaunin fibers was observed in the subepidermal region, with a reconstitution of the papillary structure of the dermal-epidermal junction. Elastotic deposits in the deep dermis were substituted by a normal elastin fiber network. The coordinated removal of the pathologic deposits of old elastic fibers and their substitution by the normal ones was concomitant with activation of cathepsin-K and MPP12, and with expansion of the M2 macrophage infiltration.

MedicalResearch.com: What should readers take away from your report?

Response: This study has demonstrated ADSC to remodeling the skin extra cellular matrix, mainly in the elastic system.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Response: Based on these findings, the future of thisresearch line aims to create new possibilities in regenerative cell therapy not only in skin diseases, but also in other clinical applicability in the case of organs and tissues with reduction and / or alteration in the elastic system (ex: aneurysms, cardiac valve disease and others), with a better understanding of the mechanisms involved and the control of these processes.

MedicalResearch.com: Is there anything else you would like to add? Any disclosures?

Response: It is interesting to be able, in future studies, to evaluate other mechanisms involved and the duration of effects regenerative effects on skin treated with ADSC. Another question could be considered: optimized ADSC (quantity) / area with the tissue effect found. We have not any to disclosure. This study was developed by federal university of Rio de Janeiro-Brasil and Verona University-Italy

The Phase 2 study will assess the safety and efficacy of Longeveron's stem cell treatment under Japan's accelerated regulatory pathway for regenerative medicine.

MIAMI, FL, USA I June 1, 2020 I Longeveron LLC announced today that Japan's Pharmaceutical and Medical Devices Agency (PMDA) (the Japanese agency akin to the United States' Food & Drug Administration) approved a Clinical Trial Notification (CTN) application (akin to an Investigational New Drug Application or "IND" in the US regulatory system), approving the initiation of a Phase 2 clinical trial evaluating the safety and efficacy of Longeveron's Mesenchymal Stem Cells (LMSCs) for the treatment of Aging Frailty in Japanese patients. This is another key milestone for Longeveron's Aging Frailty program, which includes two ongoing Phase 2 clinical trials in the U.S.

"We are extremely pleased to achieve this significant milestone," said Geoff Green, President of Longeveron."This study is designed to determine whether the transplant of donor-derived mesenchymal stem cells can improve healthspan in mild to moderately frail patients, thereby improving functionality and potentially lowering their risk of disability, and dependence on others for care."

Aging Frailty is a common, but reversible, life-threatening geriatric condition affecting millions of Japanese over the age of 65.Frail individuals are vulnerable to adverse health outcomes compared to their age-matched peers despite sharing similar comorbidities and demographics.Clinically, frailty manifests as a combination of symptoms that may include loss of muscle and decreased strength, slowed walking (sarcopenia), lower activity and energy levels, poor endurance, nutritional deficiencies, weight loss and fatigue.Collectively, these lead to overall decline in functionality, and increased risk of disability, dependency, and death.

"The biology of frailty is complex, and includes diminished stem cell activity, reduced ability to repair and regenerate tissue, and immunosenescence (deterioration of the immune system) and chronic systemic inflammation," said Dr. Anthony Oliva, Senior Scientist at Longeveron. "LMSCs have multiple mechanisms of action that can potentially address all of these issues, and thus make them extremely attractive as a therapeutic candidate for the unmet medical need of Aging Frailty."

The planned study is an investigator-initiated, randomized, double-blind, placebo-controlled design,and will be conducted at Juntendo University Hospital (Tokyo) and Japan's National Center for Geriatrics and Gerontology (NCGG) in Nagoya.The study's Principal Investigator, Dr. Hidenori Arai, President of the NCGG, commented that "Japan has one of the oldest and fastest aging societies in the world, with nearly 30% of Japan's citizens over the age of 65.Preventing and reversing functional decline associated with frailty is one of the nation's top priorities, and Longeveron's regenerative medicine approach is an exciting and innovative potential therapeutic option.With the disproportionate infection and mortality rate of older people with COVID-19 and Influenza infection, it is critically important to rapidly test treatments that may be effective."

In Japan, the "Pharmaceutical and Medical Device Act" and the "Act on the Safety of Regenerative Medicine" came into effect in 2014. Under this system, a "Time-limited Conditional Approval" option exists, which allows a manufacturer to conditionally sell regenerative medicine products while proceeding with its Phase 3 clinical trial.

Longeveron's Aging Frailty Research Program

Longeveron sponsors the most extensive and advanced Aging Frailty clinical research program in the world, with more than 200 patients treated with LMSCs worldwide.In the U.S., two clinical trials are currently ongoing:

For instance, the University of Washingtons Institute for Stem Cell and Regenerative Medicine (ISCRM) has attempted to manipulate stem cells to heal eye, kidney, and heart injuries. A number of diseases such as Alzheimers, spinal cord injury, Parkinsons, diabetes, stroke, retinal disease, cancer, rheumatoid arthritis, and neurological diseases can be successfully treated via stem cell therapy. Therefore, stem cell assays will exhibit growing demand.

Another key development in the stem cell assay market is the development of innovative stem cell therapies. In April 2017, for instance, the first participant in an innovative clinical trial at the University of Wisconsin School of Medicine and Public Health was successfully treated with stem cell therapy. CardiAMP, the investigational therapy, has been designed to direct a large dose of the patients own bone-marrow cells to the point of cardiac injury, stimulating the natural healing response of the body.

Newer areas of application in medicine are being explored constantly. Consequently, stem cell assays are likely to play a key role in the formulation of treatments of a number of diseases.

Researchers are learning more about genetic aberrations common in the rare but clinically aggressive hematological cancer blastic plasmacytoid dendritic cell neoplasm. There is one targeted therapy approved by the U.S. Food and Drug Administration: Elzonris (tagraxofusp-erzs, Stemline). However, more treatment options are needed to improve the cancers clinical outcome, according to a review published May 2020 in Critical Reviews Oncology/Hematology.1

Dermatologists might be the first providers to encounter patients with blastic plasmacytoid dendritic cell neoplasm because more than 70% of these patients have cutaneous lesions. Those lesions often are asymptomatic and vary in size. The skin lesions tend to have nodules, plaques or bruise-like areas, a brown to violet color and might be solitary or multifocal, according to the authors.

Blastic plasmacytoid dendritic cell neoplasm often originates from type 2 myeloid-derived resting plasmacytoid dendritic cell precursors. Recent research suggests providers can diagnose the cancer when patients express at least four of five plasmacytoid dendritic cell specific markers, CD4, CD56, CD123, TCL1 and BDCA-2, without expressing myeloid, T-cell or B-cell lineage markers.

Commonly, [blastic plasmacytoid dendritic cell neoplasm] is characterized by high CD123 expression, aberrant NF-B [nuclear factor-B] activation, dependence on TCF4-/BRD4-network, and deregulated cholesterol metabolism, they wrote.

Despite advancing knowledge about the cancer type, patients median overall survival remains at 12 to 14 months, according to the paper. Conventional treatment approaches include chemotherapy, radiotherapy and ultimately hematopoietic stem cell transplantation. The challenges with conventional therapies are while blastic plasmacytoid dendritic cell neoplasm is sensitive to some chemotherapy regimens, patient relapse is high at more than 60%. And many patients with blastic plasmacytoid dendritic cell neoplasm are too old or frail to have intensive chemotherapy or hematopoietic stem cell transplantation, according to the authors.

Recently, the most attractive agent for [blastic plasmacytoid dendritic cell neoplasm] is tagraxofusp, which is composed of the catalytic and translocation domains of diphtheria toxin (DT) fused to interleukin-3 (IL-3), the authors wrote.

Blastic plasmacytoid dendritic cell neoplasm cells overexpress interleukin-3 receptor subunit alpha (IL3RA, also called CD123). Elzonris, or tagraxofusp-erzs, is a CD123-directed cytotoxin given intravenously, which is used to treat blastic plasmacytoid dendritic cell neoplasm in adults and in pediatric patients 2 years and older.

Researchers reported in a study of 47 blastic plasmacytoid dendritic cell neoplasm patients published in 2019 in the New England Journal of Medicine that tagraxofusp led to clinical responses in untreated and relapsed patients.2 The overall response rate with tagraxofusp was 90% and the primary outcome of complete response and clinical complete response was 72% among the previously untreated patients. Overall response was 67% in the previously treated patients. Serious adverse events including capillary leak syndrome, hepatic dysfunction and thrombocytopenia were common, according to the NEJM paper.

More targeted therapies are needed to treat blastic plasmacytoid dendritic cell neoplasm, but many potential therapeutic agents are not advancing to clinical trials, according to authors of the paper in Critical Reviews Oncology/Hematology.

Common blastic plasmacytoid dendritic cell neoplasm characteristics are genetically heterogeneous and provide valuable drug targets, according to the authors.

Apart from aberrant activation of NF-B signaling pathway, which is highly dependent on TCF4- and BRD4- transcriptional networks, cholesterol metabolism deregulation and CD123 expression, defects of DNA damage repair and mitosis are new, potential common features of the cancer. Corresponding therapies might be promising, the authors wrote.

Venetoclax, anti-CD123 CAR-T, XmAb14045 and IMGN632 are in clinical trials for blastic plasmacytoid dendritic cell neoplasm. But the authors noted that bortezomib, lenalidomide, 5-aza and pralatrexate could easily be pushed to the front line of the cancers treatment.

The art (and existing science) of regenerative medicine in equine practice, and whats to come

Regenerative therapy is an umbrellaterm encompassing any method that encourages the body to self- heal. Because it is drawing onits own properties, healing tissue more closely resembles native tissue than weak, disorganized scar tissue typically seen post-injury.

The goal is to allow restoration of normal function and structure of the injured tissue to allow horses to perform at their previous level, whatever that might be, with a reduced risk of reinjury, says Kyla Ortved, DVM, PhD, Dipl. ACVS, ACVSMR, assistant professor of large animal surgery at the University of Pennsylvanias New Bolton Center, in Kennett Square.

She says the three main components of regenerative medicine that help tissues self-heal include:

A specific therapy may incorporate some or all three of these components, says Ortved.

Due to the regenerative therapy industrys popularity and continued growth, many articles weve published review recent laboratory studies about stem cell production and data on efficacy andsafety (you can find them at TheHorse.com/topics/regenerative-medicine). Here, well review the basics of three regenerative modalities commonly used in equine medicine and when veterinarians and horse owners might consider each.

With this approach the practitioner collects blood from a horse and processes it using a commercial system that concentrates the platelets. When he or she injects that concentrated platelet product back into the horse, granules within the platelets release an array of growth factors that aim to facilitate and modulate the healing process. Specifically, granule-derived growth factors encourage target tissue cells at the injury site to migrate and proliferate, improve extracellular matrix synthesis, and stimulate blood vessel development.

Recently, leukocyte-reduced PRP hasbecome many equine veterinarians PRP product of choice. These preparations contain fewer white blood cells (leukocytes) and, reportedly, inflammatory mediators than normal PRP products do. These mediators break tissues down, effectively counteracting the anabolic (tissue-building) effects of the platelets and their granules.

Veterinarians can easily prepare ACS by collecting a blood sample from the patient, then incubating it with special commercially available glass beads to stimulate interleukin-1 receptor antago- nist protein (IRAP) production. Theythen inject the resultant IRAP-rich serumsample back into the patient at the target location or injury site. This protein blocks the action of interleukin-1, a powerful and damaging pro-inflammatory mediator. Additionally, glass bead incubation stimulates the production of anti-inflammatory mediators and growth factors similar to those found in PRP.

Ortved says its important to remember that all biologics, including PRP and IRAP, contain various concentrations of growth factors and bioactive protein.

Remember, they are made from your horses blood and, therefore, containall of the components in blood, just in varying concentrations, she says.

Regenerative therapies that contain highconcentrations of IRAP include IRAP II, autologous protein solution (APS), and bone marrow aspirate concentrate (BMAC).

In certain tissues, such as adipose (fat) and bone marrow, we can find specific cells that have the ability to self-renew and grow more than 200 types of body cells. Veterinarians can isolate these cells, called stem cells or progenitor cells, and either:

Perhaps more important than theirability to differentiate into other celltypes, stem cells have powerful anti-inflammatoryproperties and play acentral role in coordinating healing in alltypes of tissues through cell-to-cell signaling,Ortved says.

Which of these three modality typeswill provide the most benefit to yourhorse depends on a variety of factors thatyou and your veterinarian will consider.

Most people are seeking the secret to anti-ageing, but did you ever wonder how the skin actually ages or how you could slow the process down?

Ageing is a natural process accompanied by a continuous alteration of the body. Your body produces visible changes in its structure, function and vulnerability to environmental stress and disease. Genetics, as well as the lifestyle we lead, play a big role in the ageing process.

Your skin is an organ, and its function is to regulate the excretion of metabolic waste products, regulate the bodies temperature as well as containing receptors for pain, tactile sensation, and pressure. Therefore, the health and appearance of your skin, like the health of your other organs correspond with your lifestyle and dietary habits, as well as with age-related factors such as the imbalance of hormones.

Ageing of the skin can be influenced by many factors including ultraviolet radiation, excess alcohol consumption, tobacco abuse, and environmental pollution.

What a lot of people dont realise is that as their body weight increases and their blood sugar levels rise, biochemical reactions interrupt the structural framework of their skin. With all these factors combined they lead to cumulative deterioration in the appearance of the skin as well as the function of the skin.

Within the skin ageing is associated with a loss of fibrous tissue, a slower rate of cellular renewal, and a reduced vascular and glandular network. The barrier function that maintains cellular hydration also becomes impaired. The subcutaneous tissue (known as the hypodermis or the third layer of the skin) flattens.

The rate at which these functions decline can be more than 50% by middle age depending upon ones genetic makeup, lifestyle and normal physiological functions within the skin. If we dont take action to support our skins intrinsic defence systems, the youthful qualities of our skin will deteriorate rapidly. Luckily for us, we can harness insights gathered through the latest scientific innovations and slow or potentially reverse the signs and symptoms of accelerated skin ageing.

Intrinsic skin ageing is primarily determined by genetic factors, hormonal imbalances and metabolic reactions like oxidative stress. Signs of intrinsic ageing include skin sagging, thinning and cracking, and the appearance of fine lines and wrinkles.

There are numerous external factors that affect the skin and cause signs and symptoms of premature ageing. Generally, most premature ageing is caused by over-exposure to the suns UV rays. However, there are other contributing factors, for example, atmospheric factors such as air pollution, visible light and infrared radiation. Lifestyle choices such as smoking, chronic stress and excessive alcohol consumption can lead to older-looking skin.

The most common signs of extrinsic ageing are thinning of the skin, laxity, fragility and the increased appearance of wrinkles.

As the skin is a visual organ, the beauty industrys main objective is to improve the appearance of skin with extensive topical treatments and products. However, often overlooked is the need to support the health and beauty of the skin from within.

Ideally one should centre their diet upon fruits, vegetables, whole grains, legumes, monounsaturated fats (like those found in olive oil), and a healthy ratio of omega-3 to omega-6 polyunsaturated fatty acids. Generally, consumption of shellfish, fish rich in omega 3 fatty acids, regular tea drinking, and greater consumption of fruits and vegetables have been known to be associated with improved skin health.

Gut health is crucial to healthy skin. The human skin hosts a variety of microorganisms, collectively known as the skin microbiota. Within the skin, there is a complex network of interactions between the microbes and cells. Friendly bacteria, such as Lactobacillus and Bifidobacteria are well researched for effectively treating infections, promoting healthy immunity, and reducing inflammation in the skin. Oral pre- and probiotics help to rebalance the skin microbiota and optimise the skin barrier function.

In addition, oral probiotics boost cellular antioxidant capacity and combat inflammation in general. Probiotics also help to neutralise toxic byproducts, defend the lining of the intestine, increase the bioavailability of some nutrients and reinforce the intestinal barrier against infectious microbes that may harm healthy skin.

Cosmeceuticals are topical products that exert both cosmetic and therapeutic benefits which have continued to evolve in order to ward off the signs of skin ageing. Some of the most popular topicals include exfoliating and depigmenting agents, antioxidants and regenerating products, such as peptides and stem cells.

Sunscreens (with dual protection against UVA and UVB in a photostable complex) are the most important topical as they protect us from the UV damage caused by the sun. Sun exposure is definitely one of the biggest contributing factors to premature ageing and is actually known as photo-ageing.

Another phenomenal topical is retinoids which have proven their safety and efficacy in reducing photo-damaged skin and are a popular treatment for anti-ageing. Retinoids help combat and reverse the visual effects of ageing, such as wrinkles, laxity, and discolouration. Retinoids accelerate cell turnover and can also improve blemishes and the appearance of pores.

The use of alpha-hydroxy acids (AHAs) has also been known to improve skin texture and reduce the signs of ageing by promoting the shedding of our superficial dead skin cells which in turn helps to restore hydration and a smoother texture. Whats nice about alpha-hydroxy acids is that they can pretty much treat any skin condition or concern because there are so many different types of acids. Theres literally something for everything. The most common ingredients used in product formulations and peels include citric acid, glycolic acid, lactic acid, malic acid, pyruvic acid as well as tartaric acid.

Antioxidants are being increasingly used in anti-ageing skincare. Topical antioxidants are effective in fending off damaging free radicals and reducing inflammation within the skin. A few popular ones used are ascorbic acid (vitamin C,) tocopherols (vitamin E,) alpha-lipoic acid and coenzyme Q10. Emerging natural antioxidants proving effective include EGCG (from green tea), resveratrol, Centella Asiatica (Gotu Kola,) proanthocyanidins (grapeseed,) curcumin, pomegranate, silymarin/silibinin (milk thistle), coffeeberry, melatonin, and marine-based ingredients.

Within the skin, the deterioration of collagen results in the formation of protein fragments, called peptides. These peptides are then recognised by collagen-producing cells, which respond by increasing collagen production in order to repair the damaged skin. However, as we age this positive feedback between skin breakdown and the initiation of new collagen formation becomes inefficient. Therefore by applying specialised peptides to your skin topically you can effectively trick collagen-producing cells into boosting collagen production. There are many other active ingredients used in topical products that are focused on anti-ageing among other things.

So basically all we need to do is protect the skin from the inside by consuming nutrient-packed foods as well as reducing our exposure to extrinsic factors that cause premature ageing along with using topical skincare products. Not as difficult as we may have thought, hey?

Ageing: An expos on what really causes us to show our age - The South African

In the UK 50,000 people have a spinal cord injury (SCI)[1]

Every year there are 2,500 new cases of SCI in the UK[1]

20-30% of people with SCI show clinically significant signs of depression[2]

People with spinal cord injury are two to five times more likely to die prematurely[2]

50kpeople in the UKhave spinal cord injury

A traumatic injury to the spine can cause a bruise, partial or complete tear in the spinal cord, leading to partial or total loss of feeling/movement in various body parts. The most common sites of injury are the cervical and thoracic areas.

Generally, spinal cord injuries (SCI) affect areas lower than the point of damage, so the higher the damage, the more movement and sensation will be lost. Spinal cord injury can even result in paraplegia and tetraplegia[3], although severity and recovery rate varies widely depending on the location and extent of the injury.

To aid recovery and lessen the risk of developing associated conditions, its essential that each patient receives appropriate rehabilitation and health maintenance support.

Stem cell therapy is rapidly evolving and offering treatment for spinal-cord injuries (SCI). Although there is no current treatment available to restore injury-induced loss of function, evidence is building that stem cell infusions into the spine may support spinal cord repair.

Positive results have been observed in phase I/II clinical trials at Puerta de Hierro Hospital in Madrid[4]. 12 patients were given doses of the new drug NC1 made from autologous mesenchymal stromal cells (MSCs) and autologous plasma. All 12 patients experienced improvements in sensitivity and 50% showed greater motor activity, decreased spasms and improved sexual function.

Since this clinical trial took place, the NC1 drug has been approved by the Spanish Agency of Medicines. However, there is still more research to be done for stem cell therapy to be widely administered for repairing spinal cord injury.

Stem cell therapy and spinal cord injury (SCI) | Future ...

The spinal cord is a long, fragile, tube-like nervous structure that connects the brain with peripheral nerves. Damage to the spinal cord, by trauma or other means, consequently results in severe motor- and sensory deficits that usually lead to the inability to move and feel. Accidents are the most common cause of Spinal Cord Injury with catastrophic consequences for the life of the patient and their relatives. While conservative therapies aim to stabilize the patient, functional recovery in most cases is minimal.

Both preclinical and clinical studies have shown improved recovery of spinal cord injury patients when the therapy was combined with a suitable stem cell therapy. Our clinic provides access to the most advanced clinically available combination of stem cell therapies.

Spinal trauma can disrupt ascending and descending axonal pathways that lead to: inflammation, demyelination and loss of neural cells (neurons). Depending on the site of injury, functional disorders induced by cellular damage usually result in the inability to move, sensory loss and/or lack of autonomous nervous system control.

Fully regenerative therapies for spinal trauma do not exist yet. However, very promising results have been obtained with stem cell transplantation in patients with spinal trauma. The use ofMesenchymal Stem Cells (MSCs) in Spinal Cord Injury has been extensively reviewed. Experiments with MSCs have shown that their abilities to stimulate repair processes in spinal cord injury are due to the paracrine secretion of the stem cells. After 21 days of observations, even though the MSCs had not been incorporated into the regenerated host tissue, there was a significant improvement in functional recovery, from as early as one week after the treatment with MSCs.

-- Peer-reviewed publication in Alzheimer's & Dementia: Translational Research & Clinical Interventions validates potential of drug discovery platform and ability to study early stages of disease pathology --

Hesperos Inc., pioneers of the Human-on-a-Chip in vitro system, today announced a new peer-reviewed publication that describes how the companys functional Human-on-a-Chip system can be used as a drug discovery platform to identify therapeutic interventions targeting the preclinical stages of Alzheimers disease (AD) and mild cognitive impairment (MCI). The manuscript, titled "A human induced pluripotent stem cell-derived cortical neuron human-on-a-chip system to study A42 and tau-induced pathophysiological effects on long-term potentiation," was published this week in Alzheimer's & Dementia: Translational Research & Clinical Interventions. The work was conducted in collaboration with the University of Central Florida and with David G. Morgan, Ph.D., Professor of Translational Neuroscience at Michigan State University, and expert in AD pathology.

To date, more than 100 potential therapeutics in development for AD have been abandoned or failed during clinical trials. These therapeutics relied on research conducted in preclinical animal studies, which often are unable to accurately capture the full spectrum of the human disease phenotype, including differences in drug metabolism and excretion between humans and animals. Therefore, there is a need for human models, especially those that accurately recapitulate the functional impairments during the preclinical phases of AD and MCI.

"Hesperos offers a breakthrough technology that provides a human cell-based assay based on cognitive function metrics to evaluate drugs designed to restore cognition at early stages of the Alzheimers continuum," said Dr. Morgan. "This system can serve as a novel drug discovery platform to identify compounds that rescue or alleviate the initial neuronal deficits caused by A1-42 and/or tau oligomers, which is a main focus of clinical trials."

In 2018, Hesperos received a Phase I Small Business Innovation Research (SBIR) grant from the National Institute on Aging (NIA) division within the US National Institutes of Health (NIH) to help create a new multi-organ human-on-a-chip model for testing AD drugs. Research conducted under this grant included a study to assess therapeutic interventions based on functional changes in neurons, not neuronal death.

In the recent Alzheimer's & Dementia publication, Hesperos describes its in vitro human induced pluripotent stem cell (iPSC)-derived cortical neuron human-on-a-chip system for the evaluation of neuron morphology and function after exposure to toxic A and tau oligomers as well as brain extracts from AD transgenic mouse models.

"Researchers are now focusing on biomarker development and therapeutic intervention before symptoms arise in AD and MCI," said James Hickman, Ph.D., Chief Scientist at Hesperos and Professor at the University of Central Florida. "By studying functional disruption without extensive cell loss, we now have a screening methodology for drugs that could potentially evaluate therapeutic efficacy even before the neurodegeneration in MCI and AD occurs."

The researchers found that compared to controls, treatment with toxic A and tau oligomers or brain extracts on the iPSC cortical neurons significantly impaired information processing as demonstrated by reduction in high-frequency stimulation-induced long-term potentiation (LTP), a process that is thought to underlie memory formation and learning. Additionally, oligomer and brain extract exposure led to dysfunction in iPSC cortical neuron electrophysiological activity, including decreases in ion current and action potential firing.

While exposure to the toxic oligomers and brain extracts caused morphological defects in the iPSC cortical neurons, there was no significant loss in cell viability.

"Clinical success for AD therapies has been challenging since preclinical animal studies often do not translate to humans," said Michael L. Shuler, Ph.D., Chief Executive Officer of Hesperos. "With our recent study, we are now one step closer in developing an AD multi-organ model to better evaluate drug metabolism in the liver, penetration through the blood-brain barrier and the effects on neuronal cells."

AD is a progressive disease that is characterized by memory loss and deterioration of cognitive function. Preclinical AD is the first stage of the disease, and it begins long before any symptoms become apparent. It is thought that symptoms do not manifest until there is a significant death of neuronal cells, which is caused by the aggregation of toxic amyloid beta (A) and tau oligomers, typically during the earliest stages of the disease. Unfortunately, treatment after the diagnosis of MCI may be too late to reverse or modify disease progression.

Central nervous system comprises brain and spinal cord, and is responsible for integration of sensory information. Brain is the largest and one of the most complex organs in the human body. It is made up of 100 billion nerves that communicate with 100 trillion synapses. It is responsible for the thought and movement produced by the body. Spinal cord is connected to a section of brain known as brain stem and runs through the spinal canal. The brain processes and interprets sensory information sent from the spinal cord. Brain and spinal cord serve as the primary processing centers for the entire nervous system, and control the working of the body. Neuroprosthetics improves or replaces the function of the central nervous system.

Neuroprosthetics, also known as neural prosthetics, are devices implanted in the body that stimulate the function of an organ or organ system that has failed due to disease or injury. It is a brain-computer interface device used to detect and translate neural activity into command sequences for prostheses. Its primary aim is to restore functionality in patients suffering from loss of motor control such as spinal cord injury, multiple sclerosis, amyotrophic lateral sclerosis, and stroke. The major types of neuroprosthetics include sensory implants, motor prosthetics, and cognitive prosthetics. Motor prosthetics support the autonomous system and assist in the regulation or stimulation of affected motor functions.

Similarly, cognitive prosthetics restore the function of brain tissue loss in conditions such as paralysis, Parkinsons disease, traumatic brain injury, and speech deficit. Sensory implants pass information into the bodys sensory areas such as sight or hearing, and it is further classified as auditory (cochlear implant), visual, and spinal cord stimulator. Some key functions of neuroprosthetics include providing hearing, seeing, feeling abilities, pain relief, and restoring damaged brain cells. Cochlear implant is among the most popular neuroprosthetics. In addition, auditory brain stem implant is also a neuroprosthetic meant to improve hearing damage.

North America dominates the global market for neuroprosthetics due to the rising incidence of neurological diseases and growth in geriatric population in the region. Asia is expected to display a high growth rate in the next five years in the global neuroprosthetics market, with China and India being the fastest growing markets in the Asia-Pacific region. Among the key driving forces for the neuroprosthetics market in developing countries are the large pool of patients, increasing awareness about the disease, improving healthcare infrastructure, and rising government funding in the region.

Increasing prevalence of neurological diseases such as traumatic brain injury, stroke and Parkinsons disease, rise in geriatric population, increase in healthcare expenditure, growing awareness about healthcare, rapid progression of technology, and increasing number of initiatives by various governments and government associations are some key factors driving growth of the global neuroprosthetics market. However, factors such as high cost of devices, reimbursement issues, and adverse effects pose a major restraint to the growth of the global neuroprosthetics market.

Innovative self-charging neural implants that eliminate the need for high risk and costly surgery to replace the discharge battery and controlling machinery with thoughts would help to develop opportunities for the growth of the global neuroprosthetics market.

Gracell Announces Two Presentations at the Annual Meeting of American Society of Clinical Oncology (ASCO) - PRNewswire

Acute lung injury (ALI) is a devastating disease process involving pulmonary edema and atelectasis caused by capillary membrane injury [1]. The main clinical manifestation is the acute onset of hypoxic respiratory failure, which can subsequently trigger a cascade of serious complications and even death [2]. Thus, ALI causes a considerable financial burden for health care systems throughout the world. ALI can result from various causes, including multiple traumas, large-volume blood transfusions, and bacterial and viral infections [2, 3]. A variety of viruses, including influenza virus, coronavirus (CoV), adenovirus, cytomegalovirus (CMV), and respiratory syncytial virus (RSV), are associated with ALI [4]. Importantly, most viruses, whose hosts are various animal species, can cause severe and rapidly spreading human infections. In the early 2000s, several outbreaks of influenza virus and CoV emerged, causing human respiratory and intestinal diseases worldwide, including the more recent SARS-CoV-2 infection [5,6,7]. To date, SARS-CoV-2 has affected more than 80,000 people, causing nearly 3300 deaths in China and more than 1,800,000 people, causing nearly 110,000 deaths all over the world (http://2019ncov.chinacdc.cn/2019-nCoV/).

Infectious respiratory diseases caused by different viruses are associated with similar respiratory symptoms ranging from the common cold to severe acute respiratory syndrome [8]. This makes the clinical distinction between different agents involved in infection very difficult [8, 9]. Currently, the clinical experience mainly includes antibacterial and antiviral drug treatment derived from handling several outbreaks of influenza virus and human CoVs. Numerous agents have been identified to inhibit the entry and/or replication of these viruses in cell culture or animal models [10]. Although these antiviral drugs can effectively prevent and eliminate the virus, the full recovery from pneumonia and ALI depends on the resistance of the patient. Recently, stem cell-based therapy has become a potential approved tool for the treatment of virus-induced lung injury [11,12,13]. Here, we will give a brief overview of influenza virus and CoVs and then present the cell-based therapeutic options for lung injury caused by different kinds of viruses.

Influenza virus and human CoV are the two most threatening viruses for infectious lung injury [14]. These pathogens can be transmitted through direct or indirect physical contact, droplets, or aerosols, with increasing evidence suggesting that airborne transmission, including via droplets or aerosols, enhances the efficiency of viral transmission among humans and causes uncontrolled infectious disease [15]. Throughout human history, outbreaks and occasional pandemics caused by influenza virus and CoV have led to approximately hundreds of millions of deaths worldwide [16].

Influenza virus is a well-known human pathogen that has a negative-sense RNA genome [17]. According to its distinct antigenic properties, the influenza virus can be divided into 4 subtypes, types A, B, C, and D. Influenza A virus (IAV) lineages in animal populations cause economically important respiratory disease. Little is known about the other human influenza virus types B, C, and D [18]. Further subtypes are characterized by the genetic and antigenic properties of the hemagglutinin (HA) and neuraminidase (NA) glycoproteins [19]. Sporadic and seasonal infections in swine with avian influenza viruses of various subtypes have been reported. The most recent human pandemic virusesH1N1 from swine and H5N1 from aviancause severe respiratory tract disease and lung injury in humans [20, 21].

CoVs, a large family of single-stranded RNA viruses, typically affect the respiratory tract of mammals, including humans. CoVs are further divided into four genera: alpha-, beta-, gamma-, and delta-CoVs. Alpha- and beta-CoVs can infect mammals, and gamma- and delta-CoVs tend to infect birds, but some of these viruses can also be transmitted to mammals [22]. Human CoVs were considered relatively harmless respiratory pathogens in the past. Infections with the human CoV strains 229E, OC43, NL63, and HKU1 usually result in mild respiratory illness, such as the common cold [23]. In contrast, the CoV responsible for the 2002 severe acute respiratory syndrome (SARS-CoV), the 2012 Middle East respiratory syndrome CoV (MERS-CoV), and, more recently, the SARS-CoV-2 have received global attention owing to their genetic variation and rapid spread in human populations [5,6,7].

Usually, the influenza virus can enter the columnar epithelial cells of the respiratory tract, such as the trachea, bronchi, and bronchioles. Subsequently, the influenza virus begins to replicate for an asymptomatic period of time and then migrate to the lung tissue to cause acute lung and respiratory injury [24]. Similar to those with influenza virus infection, patients with SARS, MERS, or SARS-CoV-2 present with various clinical features, ranging from asymptomatic or mild respiratory illness to severe ALI, even with multiple organ failure [5,6,7]. The pathogenesis of ALI caused by influenza virus and human CoV is often associated with rapid viral replication, marked inflammatory cell infiltration, and elevated proinflammatory cytokine/chemokine responses [25]. Interestingly, in IAV- and human CoV-infected individuals, the pulmonary pathology always involves diffuse alveolar damage, but viral RNA is present in only a subset of patients [26]. Some studies suggest that an overly exaggerated immune response, rather than uncontrolled viral spread, is the primary cause in fatal cases caused by virus infection [27]. Several immune cell types have been found to contribute to damaging host responses, providing novel approaches for therapeutic intervention [28].

IAV infection, the most common cause of viral pneumonia, causes substantial seasonal and pandemic morbidity and mortality [29]. Currently, antiviral drugs are the primary treatment strategy for influenza-induced pneumonia. However, antiviral drugs cannot repair damaged lung cells. Here, we summarize the present studies of stem cell therapy for influenza virus-induced lung injury.

Mesenchymal stem/stromal cells (MSCs) constitute a heterogeneous subset of stromal regenerative cells that can be harvested from several adult tissue types, including bone marrow, umbilical cord, adipose, and endometrium [30]. They retain the expression of the markers CD29, CD73, CD90, and CD105 and have a rapid proliferation rate, low immunogenicity, and low tumorigenicity [30]. MSCs also have self-renewal and multidifferentiation capabilities and exert immunomodulatory and tissue repair effects by secreting trophic factors, cytokines, and chemokines [31]. Due to these beneficial biological properties, MSCs and their derivatives are attractive as cellular therapies for various inflammatory diseases, including virus-induced lung injury.

Several studies on IAV-infected animal models have shown the beneficial effects of the administration of different tissue-derived MSCs [32,33,34,35]. H5N1 virus infection reduces alveolar fluid clearance (AFC) and enhances alveolar protein permeability (APP) in human alveolar epithelial cells, which can be inhibited by coculture with human bone marrow-derived MSCs (BMSCs) [32]. Mechanistically, this process can be mediated by human BMSC secreted angiopoietin-1 (Ang1) and keratinocyte growth factor (KGF) [32]. Moreover, in vivo experiments have shown that human BMSCs have a significant anti-inflammatory effect by increasing the number of M2 macrophages and releasing various cytokines and chemokines, such as interleukin (IL)-1, IL-4, IL-6, IL-8, and IL-17 [32]. Similar anti-inflammatory effects have been achieved in another virus-induced lung injury model. The intravenous injection of mouse BMSCs into H9N2 virus-infected mice significantly attenuates H9N2 virus-induced pulmonary inflammation by reducing chemokine (GM-CSF, MCP-1, KC, MIP-1, and MIG) and proinflammatory cytokine (IL-1, IL-6, TNF-, and IFN-) levels, as well as reducing inflammatory cell recruitment into the lungs [33]. Another study on human BMSCs cocultured with CD8+ T cells showed that MSCs inhibit the proliferation of virus-specific CD8+ T cells and the release of IFN- by specific CD8+ T cells [36].

In addition, human umbilical cord-derived MSCs (UC-MSCs) were found to have a similar effect as BMSCs on AFC, APP, and inflammation by secreting growth factors, including Ang1 and hepatocyte growth factor (HGF), in an in vitro lung injury model induced by H5N1 virus [34]. UC-MSCs also promote lung injury mouse survival, increase the body weight, and decreased the APP levels and inflammation in vivo [34]. Unlike Ang1, KGF, and HGF mentioned above, basic fibroblast growth factor 2 (FGF2) plays an important role in lung injury therapy via immunoregulation. The administration of the recombinant FGF2 protein improves H1N1-induced mouse lung injury and promotes the survival of infected mice by recruiting and activating neutrophils via the FGFR2-PI3K-AKT-NFB signaling pathway [37]. FGF2-overexpressing MSCs have an enhanced therapeutic effect on lipopolysaccharide-induced ALI, as assessed by the proinflammatory factor level, neutrophil quantity, and histopathological index of the lung [38].

MSCs secrete various soluble factors and extracellular vesicles (EVs), which carry lipids, proteins, DNA, mRNA, microRNAs, small RNAs, and organelles. These biologically active components can be transferred to recipient cells to exert anti-inflammatory, antiapoptotic, and tissue regeneration functions [39]. EVs isolated from conditioned medium of pig BMSCs have been demonstrated to have anti-apoptosis, anti-inflammation, and antiviral replication functions in H1N1-affected lung epithelial cells and alleviate H1N1-induced lung injury in pigs [35]. Moreover, the preincubation of EVs with RNase abrogates their anti-influenza activity, suggesting that the anti-influenza activity of EVs is due to the transfer of RNAs from EVs to epithelial cells [35]. Exosomes are a subset of EVs that are 50200nm in diameter and positive for CD63 and CD81 [40]. Exosomes isolated from the conditioned medium of UC-MSCs restore the impaired AFC and decreased APP in alveolar epithelial cells affected by H5N1 virus [34]. In addition, the ability of UC-MSCs to increase AFC is superior to that of exosomes, which indicates that other components secreted by UC-MSCs have synergistic effects with exosomes [34].

Despite accumulating evidence demonstrating the therapeutic effects of MSC administration in various preclinical models of lung injury, some studies have shown contrasting results. Darwish and colleagues proved that neither the prophylactic nor therapeutic administration of murine or human BMSCs could decrease pulmonary inflammation or prevent the progression of ALI in H1N1 virus-infected mice [41]. In addition, combining MSC administration with the antiviral agent oseltamivir was also found to be ineffective [41]. Similar negative results were obtained in another preclinical study. Murine or human BMSCs were administered intravenously to H1N1-induced ARDS mice [42]. Although murine BMSCs prevented influenza-induced thrombocytosis and caused a modest reduction in lung viral load, murine or human BMSCs failed to improve influenza-mediated lung injury as assessed by weight loss, the lung water content, and bronchoalveolar lavage inflammation and histology, which is consistent with Darwishs findings [42]. However, the mild reduction in viral load observed in response to murine BMSC treatment suggests that, on balance, MSCs are mildly immunostimulatory in this model [42]. Although there are some controversial incidents in preclinical research, the transplant of menstrual-blood-derived MSCs into patients with H7N9-induced ARDS was conducted at a single center through an open-label clinical trial (http://www.chictr.org.cn/). MSC transplantation significantly lowered the mortality and did not result in harmful effects in the bodies of the patients [43]. This clinic study suggests that MSCs significantly improve the survival rate of influenza virus-induced lung injury.

The effects of exogenous MSCs are exerted through their isolation and injection into test animals. There are also some stem/progenitor cells that can be activated to proliferate when various tissues are injured. Basal cells (BCs), distributed throughout the pseudostratified epithelium from the trachea to the bronchioles, are a class of multipotent tissue-specific stem cells from various organs, including the skin, esophagus, and olfactory and airway epithelia [44, 45]. Previously, TPR63+/KRT5+ BCs were shown to self-renew and divide into club cells and ciliated cells to maintain the pseudostratified epithelium of proximal airways [46]. Several studies have shown that TPR63+/KRT5+ BCs play a key role in lung repair and regeneration after influenza virus infection. When animals typically recover from H1N1 influenza infection, TPR63+/KRT5+ BCs accumulate robustly in the lung parenchyma and initiate an injury repair process to maintain normal lung function by differentiating into mature epithelium [47]. Lineage-negative epithelial stem/progenitor (LNEP) cells, present in the normal distal lung, can activate a TPR63+/KRT5+ remodeling program through Notch signaling after H1N1 influenza infection [48]. Moreover, a population of SOX2+/SCGB1A/KRT5 progenitor cells can generate nascent KRT5+ cells as an early response to airway injury upon H1N1 influenza virus infection [49]. In addition, a rare p63+Krt5 progenitor cell population also responds to H1N1 virus-induced severe injury [50]. This evidence suggests that these endogenous lung stem/progenitor cells (LSCs) play a critical role in the repopulation of damaged lung tissue following severe influenza virus infection (Table2).

Taken together, the present in vitro (Table1) and in vivo (Table2) results show that MSCs and LSCs are potential cell sources to treat influenza virus-induced lung injury.

Lung injury caused by SARS, MERS, or SARS-CoV-2 poses major clinical management challenges because there is no specific treatment that has been proven to be effective for each infection. Currently, virus- and host-based therapies are the main methods of treatment for spreading CoV infections. Virus- and host-based therapies include monoclonal antibodies and antiviral drugs that target the key proteins and pathways that mediate viral entry and replication [51].The major challenges in the clinical development of novel drugs include a limited number of suitable animal models for SARS-CoV, MERS-CoV, and SARS-CoV-2 infections and the current absence of new SARS and MERS cases [51]. Although the number of cases of SARS-CoV-2-induced pneumonia patients is continuously increasing, antibiotic and antiviral drugs are the primary methods to treat SARS-CoV-2-infected patients. Similar to that of IAV, human CoV-mediated damage to the respiratory epithelium results from both intrinsic viral pathogenicity and a robust host immune response. The excessive immune response contributes to viral clearance and can also worsen the severity of lung injury, including the demise of lung cells [52]. However, the present treatment approaches have a limited effect on lung inflammation and regeneration.

Stem cell therapy for influenza virus-induced lung injury shows promise in preclinical models. Although it is difficult to establish preclinical models of CoV-induced lung injury, we consider stem cell therapies to be effective approaches to improve human CoV-induced lung injury. Acute inflammatory responses are one of the major underlying mechanisms for virus-induced lung injury. Innate immune cells, including neutrophils and inflammatory monocytes-macrophages (IMMs), are major innate leukocyte subsets that protect against viral lung infections [53]. Both neutrophils and IMMs are rapidly recruited to the site of infection and play crucial roles in the host defense against viruses. Neutrophils and IMMs can activate Toll-like receptors (TLRs) and produce interferons (IFNs) and other cytokines/chemokines [54]. There are two functional effects produced by the recruitment of neutrophils and IMMs: the orchestration of effective adaptive T cell responses and the secretion of inflammatory cytokines/chemokines [55]. However, excessive inflammatory cytokine and chemokine secretion impairs antiviral T cell responses, leading to ineffective viral clearance and reduced survival [56].

MSCs are known to suppress both innate and adaptive immune responses. MSCs have been suggested to inhibit many kinds of immune cells, including T cells, B cells, dendritic cells (DCs), and natural killer (NK) cells in vitro and in vivo [57] (Fig.1). Several molecules, including IL-1, TNF-, and INF-, most of which are produced by inflammatory cells, are reported to be involved in MSC-mediated immunosuppression [58]. Furthermore, MSCs can produce numerous immunosuppressive molecules, such as IL-6, PGE2, IDO, and IL-10, in response to inflammatory stimuli. PGE2 has been reported to mediate the MSC-mediated suppression of T cells, NK cells, and macrophages. Moreover, PGE2 has been found to act with IDO to alter the proliferation of T cells and NK cells [59]. In contrast, MSCs have come to be recognized as one type of adult stem cell actively participating in tissue repair by closely interacting with inflammatory cells and various other cell types [60]. Numerous reports have demonstrated that MSCs can release an array of growth and inhibitory factors, such as EGF, FGF, PDGF, and VEGF, and express several leukocyte chemokines, such as CXCL9, CCL2, CXCL10, and CXCL11. These factors provide an important microenvironment to activate adaptive immunity for lung repair [61]. Thus, the dual functions of MSCs may improve lung recovery after human CoV-induced ALI. Recently, MSCs was transplanted intravenously to enrolled patients with COVID-19 pneumonia. After treatment, the pulmonary function and symptoms of these patients were significantly improved. Meanwhile, the peripheral lymphocytes were increased, the C-reactive protein decreased, the level of TNF- was significantly decreased, and the overactivated cytokine-secreting immune cells disappeared. In addition, a group of regulatory DC cell population dramatically increased. Thus, the intravenous transplantation of MSCs was effective for treatment in patients with COVID-19 pneumonia [62, 63].

Stem cell therapies for treatment of influenza virus and coronavirus-induced lung injury. CoVs, coronavirus; MSCs, mesenchymal stem/stromal cells; LSCs, lung stem/progenitor cells; NK cells, natural killer cells; DC cells, dendritic cells

In addition, endogenous LSCs also play an important role in lung cell reconstitution after virus-induced ALI. In particular, TPR63+/KRT5+ airway BCs comprise approximately equal numbers of stem cells and committed precursors and give rise to differentiated luminal cells during steady state and epithelial repair after lung injury [44, 64]. Research has shown that KRT5+ cells repopulate damaged alveolar parenchyma following influenza virus infection [47]. However, there is still little evidence for the role of altered TPR63+/KRT5+ stem cells during lung injury repair caused by human CoVs.

In summary, exogenous MSCs may modulate human CoV-induced lung injury repair and regeneration through their immunoregulatory properties. These cells are capable of interacting with various types of immune cell, including neutrophils, macrophages, T cells, B cells, NK cells, and DCs. Furthermore, viral infections can activate endogenous LSCs to produce new lung cells and maintain lung function (Fig.1). Thus, we propose that MSCs and LSCs are two potential cell sources for treating human CoV-induced lung injury.
