  • iPS and ESC As ethical and safety concerns currently forbid application of iPS cells and ESCs in patients we will focus on adult mesenchymal stem cells R. D. Robbins, N. Prasain, B. F.Maier, M. C. Yoder, and R. G.Mirmira, “Inducible pluripotent stem cells: not quite ready for prime time?” Current Opinion in Organ Transplantation, vol. 15, no. 1, pp. 61–67, 2010

  • Advantages of Mesenchymal Stem cells • Autologous – harvested from the patient themselves • No major ethical constraints – unlike embryonic stem cells • Can be expanded in vitro – unlimited supply of therapeutic cells. • Does not express HLA II antigens • Strong evidence for In Vitro and In Vivo differentiation
  • Stem cells MSC Colony on day 05 Confluent Monolayer on day 15 Isolation and in vitro expansion of mesenchymal stem cells
  • Alizarin Red Staining- 21 days Control - Undifferentiated cells Differentiated cells - Nodulation 10 X 10 X
  • Osteoblast differentiation • Differentiation was seen as early as the first week of induction • Cells became flattened and showed calcium deposition and could be seen as nodules, by the formation of mineralized matrix

  • Role of mesenchymal stem cells in regenerative medicine: application to bone and cartilage repair. Granero-Molto F, Weis JA, Longobardi L, Spagnoli A. Expert Opin Biol Ther. 2008 Mar;8(3):255-68. MSC can migrate to injured tissues and some of their reparative properties are mediated by paracrine mechanisms including their immunomodulatory actions. MSC possess a critical potential for the treatment of skeletal diseases, such as osteoarthritis or fracture healing failure, where treatments are partially effective or palliative.
  • Autologous MSCs were expanded ex vitro, embedded in a collagen gel and re-implanted into areas of articular cartilage defect in osteoarthritis patients. Wakitani S, Imoto K, Yamamoto T, Saito M, Murata N, Yoneda M. Human autologous culture expanded bone marrow mesenchymal cell transplantation for repair of cartilage defects in osteoarthritic knees.

  • Osteochondral Lesions of the Knee Osteochondral Lesions of the Knee: A New One-Step Repair Technique with Bone-Marrow-Derived Cells. By Roberto Buda, MD, Francesca Vannini, MD, PhD, Marco Cavallo, MD, Brunella Grigolo, PhD, Annarita Cenacchi, MD, and Sandro Giannini, MD J Bone Joint Surg Am. 2010;92 Suppl 2:2-11 d doi:10.2106/JBJS.J.00813 Mesenchymal stem cells represent 2% to 3% of the total mononuclear cells in bone marrow and have the ability to differentiate into various lineages, including osteoblasts and chondroblasts. The rationale of the ‘‘one-step technique’’ is based on the idea of transplanting the entire bone-marrow cellular pool instead of isolated and expanded mesenchymal stem Cells.
  • Mesenchymal stem cells in arthritic diseases MSCs possess potent immunosuppression and anti-inflammation effects through secretion of various soluble factors, MSCs can influence the local tissue environment and exert protective effects with an end result of effectively stimulating regeneration in situ. Can be used for therapeutic application in degenerative joint diseases such as RA and OA. Faye H Chen and Rocky S Tuan Arthritis Research & Therapy 2008, 10:223 (doi:10.1186/ar2514)
  • Stem Cells in OA
  • ADS/ MSC in osteoarthritis • Desando and co-workers report in Arthritis Research & Therapy that intra-articular delivery of adipose- derived stem cells attenuates progression of synovial activation and joint destruction in Osteoarthritis. • Mesenchymal stem cell therapy in osteoarthritis: advanced tissue repair or intervention with smouldering synovial activation • Peter LEM van Lent* and Wim B van den Arthritis Research & Therapy 2013, 15:112 http://arthritis-research.com/content/15/2/112

  • Autologous bone marrow transplantation in patients with sub acute and chronic spinal cord injury. Centre for Cell Therapy and Tissue Repair, Charles University, Prague, Czech Republic. sykova@biomed.cas.cz Syková E, Homola A, Mazanec R, Lachmann H, Konrádová SL, Kobylka P, Pádr R, Neuwirth J, Komrska V, Vávra V, Stulík J, Bojar M. Cell Transplant. 2006;15(8-9):675-87. 20 patients with complete SCI who received transplants 10 to 467 days post injury. The follow-up examinations were done at 3, 6, and 12 months after implantation by two independent neurologists We compared intra-arterial (via catheterization of a. vertebralis) versus intravenous administration of all mononuclear cells in groups of acute (10-30 days post-SCI, n=7) and chronic patients (2-17 months post injury, n=13). Improvement in motor and/or sensory functions was observed within 3 months in 5 of 6 patients with intra-arterial application, in 5 of 7 acute, and in 1 of 13 chronic patients. It is evident that transplantation within a therapeutic window of 3-4 weeks following injury will play an important role in any type of stem cell SCI treatment.

  • 342 patients (534 hips) with Avascular Osteonecrosis at early stages (Stages I and II) Treated with core decompression and autologous bone marrow grafting obtained from the iliac crest Patients were followed up from 8 to 18 years.
  • 69 hips with stage I osteonecrosis demonstrated total resolution of osteonecrosis based on pre and postoperative MRI studies For the 371 other hips without collapse at the most recent follow up (average 12 years), the abnormal signal persisting was seen on T1 images as intralesional area of low intensity signal with a disappearance of marginal band like pattern. THR was necessary in 94 hips
  • Best indication for the procedure is symptomatic hips with osteonecrosis without collapse. Patients who had the greater number of progenitor cells transplanted in their hips had better outcomes.

  • Stem cell tracking
  • Allogenic cell transfer • Likely to form teratomas with injection of un differentiated mesenchymal cells in knee joints, cardiac and spinal cord. • As ethical and safety concerns currently forbid application of iPS cells and ESCs in patients
  • STAP cells • Stimulus triggered acquisition of pluripotency (STAP) is a cellular reprogramming phenomenon that was recently reported in two papers (Obokata, Nature, 2014a,b). • In this reprogramming process, upon strong external stimuli, neonatal somatic cells are converted into cells that express pluripotency-related genes, such as Oct3/4,and acquire the ability to differentiate into derivatives of all three germ layers in vitro and in vivo • . Yamanaka takes issue with claims STAP cells are safer than iPS option

  • Sentiments and religion
  • Research and application
  • Quote • Blood grouping is done for transfusion, • HLA typing is done for Organ transplant, • Genome mapping for oncogenes and other inheritable diseases will be required before allogenic stem cell transfer.
  • Summary • ips can cause teratomas and malignancy • Allogenic cells can be used when their genome is mapped • Autologus expanded cells may be used
  • BMSCs is a very promising tool for regenerative medicine Further engineering such osteogenic cells in scaffolds would allow us to repair bone defects Cord blood is generally used for haemopoietic disorders and not in musculoskeletal tissues Conclusion
