Stem Cell Therapy

Cell therapy involves the direct administration of cells into the body for healing purposes. The units of therapy in this approach are single cells. For regenerative medicine, the ultimate objective of cell therapy is to establish a long-term graft with the capacity to perform organ functions. A practical example is bone marrow transplantation, in which HSC are the units of therapy, engraft in the bone marrow, and repopulate the entire blood lineage.105

Intravenous administration describes the direct injection of dissociated cells into the bloodstream using a syringe. It is the simplest delivery route for cell therapies and is used for HSC therapy in the clinic. Kidney cells, however, are different from blood cells and do not typically circulate throughout the body. The kidney is furthermore a densely-packed organ with no obvious route for stem cells to traverse from the bloodstream into the nephrons. Whether kidney stem cells have the ability to engraft and regenerate the kidney after intravenous administration therefore needs to be tested in preclinical animal models. In these experiments, the kidneys are typically subjected to acute injury. This damages the glomerular filtration barrier, which can enhance penetration of cells into the kidney and subsequent engraftment.

In one example, human iPS cell-derived cells expressing a variety of NPC and adult kidney cell markers were injected into the mouse tail vein 24 hours after administration of the nephrotoxic drug cisplatin.106 Extensive engraftment was reported in proximal tubules, which coincided with a 55% reduction in urea levels in treated mice, compared with control animals administered with saline or undifferentiated iPS cells.106 These experiments suggest a possible benefit of iPS-derived kidney cells on kidney injury. However, the isolated cells were not shown to demonstrate the ability to form kidney organoids with segmented nephrons. It is therefore unclear whether the implanted cells contained bona fide NPC or whether new nephrons were actually formed.

Intravenous administration has also been applied to adult kidney cell populations. Human glomerular epithelial transitional cells (see earlier), administered intravenously into a mouse model of chemically-induced podocytopathy, were found in glomeruli, and were associated with a decrease in proteinuria.107 These cells also contributed to tubules after acute injury.80 As these cells cannot form new nephrons, this approach seeks to repair and replace, rather than to completely regenerate.

MSC can be readily obtained, for instance from a patient's adipose tissue. Intravenous administration of MSC in experimental models can have a beneficial effect on ischemia-reperfusion injury.99,102,108 This benefit can be obtained even in the absence of MSC engraftment, likely via a paracrine effect. However, MSC administered to injured kidneys do not contribute tangibly to new nephron formation and can differentiate ectopically into undesirable fat cells or fibroblasts within glomeruli.108,109 Collectively, these findings suggest that intravenous administration of cell therapeutics may provide some benefit in cases where the glomerular filtration barrier has been compromised but may also have unwanted side effects.

At the National Institutes of Health, a surgical team successfully implanted a patch of tissue made from patient cells with the goal of treating advanced dry age-related macular degeneration (AMD), also known as geographic atrophy. Dry AMD is a leading cause of vision loss among older Americans and currently has no treatment.

The patient received the therapy as part of a clinical trial that is the first in the United States to use replacement tissues from patient-derived induced pluripotent stem (iPS) cells. The surgery was performed by Amir H. Kashani, M.D., Ph.D., associate professor of ophthalmology, Wilmer Eye Institute, Johns Hopkins School of Medicine with assistance by Shilpa Kodati, M.D., staff clinician, NEI. The procedure was performed at the NIH Clinical Center in Bethesda, Maryland, under a phase 1/2a clinical trial to determine the therapys safety.

This iPS cell derived therapy was developed by the Ocular and Stem Cell Translational Research Section team led by Kapil Bharti, Ph.D., senior investigator at the National Eye Institute (NEI), part of NIH, in collaboration with FUJIFILM Cellular Dynamics Inc., and Opsis Therapeutics, based in Madison, Wisconsin. Safety and efficacy of this cell therapy was tested by the NEI preclinical team. Clinical-grade manufacturing of this cell therapy was performed at the Center for Cellular Engineering, Department of Transfusion Medicine, Clinical Center, NIH.

This surgery is the culmination of 10 years of research and development at the NEI. In the NIH lab, the patients blood cells were converted to iPS cells, which can become almost any type of cell in the body. In this case, they were programmed to become retinal pigment epithelial (RPE) cells, the type of cell that degenerates in the advanced forms of dry AMD. RPE cells nourish and support light-sensing photoreceptors in the retina. In AMD, the loss of RPE leads to the loss of photoreceptors, which causes vision loss. This work was supported by the NIH Common Fund and NEI Intramural funding.

BORDEAUX, France, Oct. 11, 2022 /PRNewswire/ --TreeFrog Therapeutics,a biotechnology company developing stem cell-derived therapies in regenerative medicine and immuno-oncology based on the biomimetic C-Stemtechnology platform, and Invetech, a global leader in the development and production ofautomated manufacturing solutionsfor cell and advanced therapies, today announced the delivery of a GMP-grade cell encapsulation device using the C-Stemtechnology. The machine will be transferred in 2023 to a contract development and manufacturing organization (CDMO) to produce TreeFrog's cell therapy candidate for Parkinson's disease, with the aim of a first-in-human trial in 2024.Over 2023, Invetech will deliver three additional GMP encapsulation devices to support TreeFrog's in-house and partnered cell therapy programs in regenerative medicine and immuno-oncology.

TreeFrogs C-Stem technology generates alginate capsules seeded with induced pluripotent stem cells (iPSCs) at very high speed. Engineered to mimic the in vivo stem cell niche, the capsules allow iPSCs to grow exponentially in 3D, and to differentiate into ready-to-transplant functional microtissues.

Blending microfluidics and stem cell biology, TreeFrog's C-Stemtechnology generates alginate capsules seeded with induced pluripotent stem cells (iPSCs) at very high speed. Engineered to mimic the in vivo stem cell niche, the capsules allow iPSCs to grow exponentially in 3D, and to differentiate into ready-to-transplant functional microtissues. And because alginate is both porous and highly resistant, encapsulated iPSCs can be expanded and differentiated in large-scale bioreactors without suffering from impeller-induced shear stress.

"TreeFrog Therapeutics introduces a breakthrough technology for cell therapy, which impacts scale, quality, as well as the efficacy and safety potential of cellular products. Automating this disruptive technology and turning it into a robust GMP-grade instrument is a tremendous achievement for our team. This deliverable is the result of a very fruitful and demanding collaboration with TreeFrog's engineers in biophysics and bioproduction over the past four years. We're now eager to learn how the neural microtissues produced with C-Stemwill perform in the clinic." Anthony Annibale, Global VP Commercial at Invetech.

Started in 2019, the collaboration between TreeFrog and Invetech led to the delivery of a prototype in October 2020. With this research-grade machine, TreeFrog demonstrated the scalability of C-Stem, moving within six months from milliliter-scale to 10-liter bioreactors. In June 2021, the company announced the production of two single-batches of 15 billion iPSCs in 10L bioreactors with an unprecedented 275-fold amplification per week, striking reproducibility and best-in-class cell quality. The new GMP-grade device delivered by Invetech features the same technical specifications. The machine generates over 1,000 capsules per second, allowing to seed bioreactors from 200mL to 10L. However, the device was entirely redesigned to fit bioproduction standards.

"With the GMP device, our main challenge was to minimize the learning curve for operators, so as to facilitate tech transfer. Invetech and our team did an outstanding job in terms of automation and industrial design to make the device both robust and easy to use. As an inventor, I am so proud of the journey of the C-Stemtechnology. Many elements have been changed and improved on the way, and now comes the time to put the platform in the hands of real-world users to make real products." Kevin Alessandri, Ph.D., co-founder and chief technology officer, TreeFrog Therapeutics

"In October 2020, we announced that we were planning for the delivery of a GMP encapsulation device by the end of 2022. Exactly two years after, we're right on time. I guess this machine testifies to the outstanding execution capacity of TreeFrog and Invetech. But more importantly, this machine constitutes a key milestone. Our platform can now be used to manufacture clinical-grade cell therapy products. Our plan is to accelerate the translation of our in-house and partnered programs to the clinic, with a focus on immuno-oncology and regenerative medicine applications." Frederic Desdouits, Ph.D., chief executive officer, TreeFrog Therapeutics

BREAKTHROUGH TECHNOLOGY FOR IPS-DERIVED CELL THERAPIES TURNED INTO GMP PLATFORM BY TREEFROG THERAPEUTICS & INVETECH - Yahoo Finance

AMSBIO has published an interview with Professor Marius Wernig from Stanford University, Pathology Stem Cell Institute that discusses what could be the worlds first widely applicable curative treatment for Epidermolysis Bullosa (EB).

This rare genetic disease causes chronic and incredibly painful skin wounds that often lead to an aggressive form of skin cancer and eventual death.

While various cell-therapy approaches have been attempted, Professor Wernig and collaborators identified the need for induced pluripotent stem cells (iPSCs), and how they could become used to treat EB in a more efficient, applicable, and commercially viable manner.

In the past, the only way Professor Wernigs research group could grow iPSCs cells with a normal karyotype over longer periods of time was on mouse feeder cells with serum. This combination of mouse cell co-culture and undefined bovine serum set was not a suitable methodology as it was almost impossible to perform in compliance with FDA safety standards.

Professor Wernig describes how StemFit Basic03 clinical grade stem cell culture medium, available from AMSBIO has allowed his research group to safely expand their cells using an FDA compliant protocol. While there are still hurdles to climb before a cure for EB is fully realised, using StemFit Basic03 has solved the challenge of reproducibly growing clinical grade iPSCs.

Read the full interview.

Completely free of animal- and human-derived components StemFit Basic03 provides highly stable and reproducible culture condition for Induced Pluripotent Stem and Embryonic Stem cells under feeder-free conditions during the reprogramming, expansion, and differentiation phases of stem cell culture. StemFit Basic03 combines high colony forming efficiency with lower than standard media volume consumption to offer cost effective colony expansion when compared to leading competitors.

Stem Cells Market Size Expected to Reach USD 19.31 Billion by 2028: Increasing Number of Clinical Trials Across the Globe - Digital Journal

Specially treated stem cells derived from a single individual have been successfully implanted into that same individuals eyes in a first-of-its-kind clinical trial testing ways to treat advanced dry age-related macular degeneration (AMD).

The therapy, currently in its first phase of testing to ensure that its safe for humans, involves harvesting and processing a persons blood cells and using them to replace the persons retinal cells that had succumbed to AMD, a leading cause of vision loss globally.

The procedure was performed by researchers from the National Eye Institute (NEI), a branch of the National Institutes of Health in Bethesda, Maryland, and from the Wilmer Eye Institute at Johns Hopkins School of Medicine in Baltimore. The NIH researchers have been working on the new treatment for a decade.

The scientists, who previously demonstrated the safety and effectiveness of the therapy in rats and pigs, took blood cells from the patient and, in the laboratory, converted them into patient-derived induced pluripotent stem (iPS) cells. These immature, undifferentiated cells have no assigned function in the body, which means they can assume many forms. The researchers programmed these particular iPS cells to become retinal pigment epithelial (RPE) cells, the type that die in AMD and lead to late-stage dry AMD.

In healthy eyes, RPE cells supply oxygen to photoreceptors, the light-sensing cells in the retina at the back of the eyeball. The death of RPE cells virtually dooms the photoreceptors, resulting in vision loss. The idea behind the new therapy is to replace dying RPE cells with patient-derived induced iPS ones, strengthening the health of the remaining photoreceptors.

Before being transplanted, the iPS-derived cells were grown in sheets one cell thick on a biodegradable scaffold designed to promote their integration into the retina. The researchers positioned the resulting patch between atrophied host RPE cells and the photoreceptors using a specially created surgical tool.

The patient received the transplanted cells during the summer and will be followed for a year as researchers monitor overall eye health, including retina stability, and whether any inflammation or bleeding develop, says Kapil Bharti, PhD, a senior investigator at the NEI and for the clinical trial.

Safety data are critical for any new drug, says Gareth Lema, MD, PhD, a vitreoretinal surgeon at New York Eye & Ear Infirmary, a division of the Mount Sinai Health System. Stem cells have added complexity in that they are living tissue, Dr. Lema says. Precise differentiation is necessary for them to fulfill their intended therapeutic effect and not cause harm."

This therapy also requires a surgical procedure to implant the cells, Lema says, adding that its an exquisitely elegant surgery, but introduces further risk of harm. For those reasons, he says, Patients must know that ocular stem cell therapies should only be attempted within the regulated environment of a nationally registered clinical trial.

The rules of a clinical trial dont generally allow specifics to be discussed this early in the process, says Dr. Bharti. Announcing that we were able to successfully transplant the cells now hopefully allows us to recruit more patients, since we can take up to 12 in this phase, he says. We also hope that it will give some optimism to patients with dry AMD and to researchers studying it.

It took seven months to develop the implanted cells, says Bharti, and although the federal Food and Drug Administration (FDA) approved the clinical trial in 2019, the onset of the COVID-19 pandemic delayed the start by two years, he says.

Macular degeneration comprises several stages of disease within the macula, the critical portion of the retina responsible for straight-ahead vision. Aging causes retinal cells to deteriorate, generating debris, or drusen, within the macula, setting the stage for early (aka dry) AMD. Geographic atrophy represents a more advanced stage. If the disease progresses to the relatively rare wet AMD, so named for the leaking of blood into the macula, central vision can be snuffed out.

Risk of AMD increases with age, particularly among people who are white, have a history of smoking, or have a family history of the disease.

Treatment to slow wet AMDs progression includes eye injections with anti-VEGF (or VEGF-A for vascular endothelial growth factor antagonists), a medication that halts the growth of unstable, leaky blood vessels in the eye. Some people may undergo photodynamic therapy, which combines injections and laser treatments.

Currently, there is no cure for dry AMD; it cant be reversed. Nor are there treatments to reliably stop its onset or progression for everyone at every stage of the disease. (Research has confirmed that a specialized blend of vitamins and minerals, available over the counter as AREDS, or Age-Related Eye Disease Studies supplements, reduces the risk of AMDs progression from intermediate to advanced stages.)

There are other, ongoing clinical trials for the treatment of dry AMD. Regenerative Patch Technologies, in Menlo Park, California, for example, is a little further along in testing a different stem cell treatment. Patients have been followed for three years, and 27 percent have shown vision improvement, says Jane Lebkowski, PhD, the companys president. There are a number of AMD clinical trials ongoing in the U.S., and patients should ask their ophthalmologists about trials that might be appropriate.

ClinicalTrials.gov, the NIHs clinical trials database, lists close to 300 AMD clinical trials at various stages in the United States.

Ferhina Ali, MD, MPH, a retinal specialist at the Westchester Medical Center in Valhalla, New York, who isnt involved in the trial, describes the newest stem cell therapy as elegant and pioneering. These are early stages but there is tremendous potential as a first-in-kind surgically implanted stem cell therapy and as a way to achieve vision gains in dry macular degeneration, Dr. Ali says.

Bharti says that in laboratory animals the implanted cells behaved as retinal cells should maintaining the retinas integrity. Over the next few years, he and his colleagues will determine whether they function effectively in humans.

Does that mean, however, that the same AMD disease process that destroyed the original retinal cells could destroy the transplanted ones? It takes 40 to 60 years to damage human cells, Bharti says, and if we get that long with the transplanted cells, well take it.
