Jorge Paz MD: Adult stem cell therapy for arthritis, sports injury, and autoimmune diseases (part 2 of 3)
Stem cell Treatment protocol for autoimmune diseases such as rheumatoid arthritis. Why stem cells must be administered systemically for autoimmune diseases. Dr. Paz elaborates on the disadvantages of same-day fat-derived stem cell treatments. He presents the scientific rationale for treating rheumatoid arthritis (RA) with fat-derived stem cells along with a published case report including patient video. Presentation of similarities between MS and RA and how MS is treated with a combination of human umbilical cord-derived stem cells and adipose stem cells. Dr. Paz discusses why MS treatment includes umbilical cord-derived stem cells.

Giving birth after stem cell treatments for spinal cord injury
Trish Stressman and her husband Scott discuss how stem cell therapy at the Stem Cell Institute in Panama allowed her to recover to the point at which she could safely give birth and care for her newborn daughter, Savannah Hope.
Prior to stem cell treatment, Trish had no core muscles and would not have been able to even safely hold a baby, let alone care for one. Since stem cells, that’s all changed. Congratulations Trish, Scott and Savannah Hope!

Medistem Advances Type 1 Diabetes Stem Cell Technology Licensed From Yale
SAN DIEGO, CA — (Marketwire) — 09/12/12 — Medistem Inc. (PINKSHEETS: MEDS) announced today completion of the first phase of a joint project with the Shumakov Research Center of Transplantology and Artificial Organs of the Russian Federation and its Russian and CIS licensee ERCell. The collaboration is based on using Endometrial Regenerative Cell (ERC) technology licensed from Yale University to treat type 1 diabetes.
Dr. Viktor Sevastianov, Head and Professor of the Institute of Biomedical Research and Technology, within the Shumakov Center, demonstrated safety and feasibility of ERC injection in experimental animal models of diabetes. Additionally, the studies demonstrated that the cell delivery technology developed by Dr. Sevastianov’s laboratory can be used to enhance growth of ERC. These experiments are part of the process for registration of “new pharmacological substances,” which is the first step towards drug approval in Russia.
“Type 1 diabetes is a significant problem in the Russian Federation. Our laboratory has been working developing various delivery formulations for cell therapy, such as SpheroGel, which is registered in Russia,” said Dr. Sevastianov. “Given that the ERC can be produced in large quantities, is a universal donor cell, and already is approved for clinical trials in both the USA and Russia, we are optimistic our collaboration will lead to a viable commercial product for the type 1 diabetes Russian population.”
Medistem discovered ERCs in 2007, and they appear to possess “universal donor” properties, allowing the cells derived from one donor can treat multiple unrelated recipients. According to Medistem’s current FDA cleared production scheme, one donor can generate 20,000 patient doses. Medistem licensed technology from Yale University for generating insulin producing cells from ERC. A publication describing the technology may be found at http://www.ncbi.nlm.nih.gov/pubmed/21878900.
“Our vision is to combine SpheroGel, which is a clinically-available cell delivery vehicle in Russia, together with Medistem’s ERC and technology from Yale University to generate a commercially-viable product for clinical trials in type 1 diabetes patients,” said Thomas Ichim, CEO of Medistem.
Medistem has outlicensed the Russian and CIS rights to ERC and related products to ERCell LLC, a St. Petersburg-based biotechnology company. Under the agreement, Medistem owns all data generated and will receive milestone and royalty payments.
“By working with leading investigators in Russia and the USA, we seek to be the leaders in a new era of medicine in Russia,” said Tereza Ustimova, CEO of ERCell.”

Fat Stem Cells are not affected by weight or age
Mojallal et al. Aesthetic Plast Surg.
Fat represents a potent source of autologous stem cells. Historically, the majority of research using autologous stem cells involved stem cells collected from the bone marrow. This source is associated with a painful extraction procedure and relatively low concentrations of mesenchymal stem cells. In contract, mini-liposuctions represent a less invasive extraction approach. Additionally, adipose tissue has been shown to contain substantially higher number of mesenchymal stem cells as well as hematopoietic stem cells and endothelial progenitor cells.
The use of fat derived stem cells has grown exponentially in recent years for numerous indications. Perhaps the largest data set for fat derived stem cells is possessed by Dr. Bob Harman from Vet Stem, who has treated a total of more than 10,000 large animals with this procedure. The Cellmedicine clinic has had an excellent track record of success using autologous fat for treatment of multiple sclerosis having treated more than 200 patients.
One of the major limiting factors of stem cell therapy using your own stem cells (autologous) is that the potency and number of stem cells is believed to decrease with age and disease. These studies, however, have been performed primarily from bone marrow sources of stem cells. Any hematologist will tell you that with age the bone marrow becomes drier and possesses less cells. Studies have shown that bone marrow stem cells from patients with diabetes or from obese patients have less activity as compared to age matched controls. There has been some thought that the stem cells in the adipose tissue are protected from age and disease. A current study (Mojallal et al. Influence of Age and Body Mass Index on the Yield and Proliferation Capacity of Adipose-Derived Stem Cells. Aesthetic Plast Surg. 2011 May 26) from the Service de Chirurgie Plastique, Reconstructrice et Esthétique in Lyon France sought to address this. The investigators assessed 42 women who were divided into two groups: age ≤ 40 or >40 and BMI ≤ 25 or >25. Fat tissue was harvested via manual lipoaspiration from the abdominal region. After centrifugation, 100 ml of lipoaspirate was sent to the laboratory for isolation and cultivation of ASCs. The investigators found that average cell yield was 0.380 × 10(6)/ml. Cell yield and proliferation capacity did not show statistically significant correlation to the age and BMI of patients, nor was there a statistically significant difference between cell yield and proliferation capacity between the different groups.
The study looked at some very basic parameters: cell number, viability and proliferative ability. It may be that adipose stem cells may exhibit differences in immune modulatory potential or differentiation potential between donors. This was not assessed. Additionally, the adipose derived cells were not assessed between donors suffering from different conditions. Despite these shortcomings, the data appears to support the hypothesis that adipose derived stem cells may have some advantages as compared to bone marrow stem cells, at least for autologous uses.
