Genesis of a novel protocol

• MSCs derived from Bone-marrow was gold standard till recently.

• ADMSCs are emerging as a platinum standard since current decade and are vastly investigated for regeneration.

• SVF derived from autologous AT is just emerging as a preferred mode of therapy with abundant literature support. This is in consonance with ICMR guidelines 2013.

1. We obtained MSCs from bone-

marrow. Found that the % was ~ 1-

2. We translated MSCs to cartilage.

This would mean therapeutically

they will lose stemness.

• We were funded by DBT to isolate and culture MSCs obtained from 22 samples of AT. This was successfully done and, was awarded best research award at BIRAC III.

• We presented the data at Sir Ganga Ram Hospital with Dr. Prof. N. K Ganguly in Chair in 2015. In brief, the following images verify that AT yielded multipotent MSCs having properties for translineage translation too.

• We were awarded Biotechnology Ignition Grant (BIG) from BIRAC, DBT, GoI to establish a novel protocol for treatment of Osteoarthritis with Stromal Vascular Fraction (SVF).

• Between 2013 till today the focus has shifted from application of ADMSCs to AT-SVF with large literature support. This includes therapy for Osteoarthritis too.

• The clinical trial began in June 2015. IEC & IC-

SCR approvals were obtained. DCGI approval

was obtained.

• The trial concluded in Nov 2016. The study is

submitted for publication to the Journal

Cytotherapy. A copy of the manuscript is

circulated.

Animal Studies – not needed

• Abundant literature support in several species of animals from murine to caprine. Ref;

Transplantation of Nonexpanded Adipose Stromal Vascular Fraction and Platelet-Rich Plasma for Articular Cartilage Injury Treatment in Mice Model

Phuc Van Pham, Khanh Hong-Thien Bui, Dat Quoc Ngo, Lam Tan Khuat, andNgoc Kim Phan1Not needed as per latest GoI guidelines for research.

Evolution to the present study; in

process

• With the above academics a study was

designed. A pilot project with six patients was

successfully carried out between 2012 – 2013.

This was presented to the expert committee

at BIRAC, DBT, GoI. The study is published in

Stem Cell: Advanced Research & Therapy.

Hard copy is circulated.

Properties of MSCs in AT

1. Anti- apoptosis

2. Angiogenesis

3. Secretion of growth factors

4. Anti-fibrosis

5. Anti- inflammatory

6. Immunonaive

Composition of SVF

1. MSCs – 30-40 %

2. CD 34+ haemopoietic stem cells

3. Endothelial precursor cells

4. T-regulatory cells

5. Macrophages

6. Smooth muscle cells

7. Pre-adipocytes

It is established that cells in SVF support regeneration of the cartilage.

Denial of Disinformation

1. Stem cell are tumorogenic.

• Denied since autologous minimally manipulated ADMSCs and AT-SVF have no such incidence.

2. Multipotent stem cells may undergo translineage translation

• Denied since autologous minimally manipulated ADMSCs and AT-SVF have no such incidence.

There is only a single incidence of bone formation at the transplanted bone-marrow stem cells.

3. Large literature support for stability of genes.

Cytokines in Platelet Rich Plasma

Advantages at SGRH

• The project will be known as SGRH – Vadodara protocol.

• A leap forward in the most researched area in stem cell therapy in present decade.

• Will help serve poor even better than as of now. Subsidy will be low and project will attract donations.

• Certain to attract medical tourism.

• For the Orthopedic surgeons:

• Huge saving of operating time

• Additional tool in the armamentarium to help even health compromised

Why the project needs SGRH

• The project has national relevance.

• GoI funds need to be deployed to yield dividends for societal benefit.

• At affordable price to most patients.

• It will be only second to Stempeutics stem cell product from India.

• It will be an in house product at SGRH – a la carte – autologous, easy to obtain.

• In full compliance with ICMR guidelines 2013.

Futuristic unfolding at SGRH

• Other Orthopedic conditions – AVN femoral

head and Osteoarthritis elsewhere: cartilage

injuries and ligamentous tears.

• Endodermal translation for Diabetes I & II.

• Neuronal translation for neuro – restoration in

neurodegenerative diseases including

Parkinson’s disease.

Conclusion

• Autologous SVF and PRP is a new potential

strategy to treat OA of human knees.

• With intra-articular injection of autologous

adipose derived SVF and autologous PRP, all

patients except one drop out improved.

• Further studies are necessary. Intra-articular

injections of autologous adipose SVF and

autologous PRP present a promising minimally

invasive option of treating OA successfully

with certain safety and high efficiency.
