-Stem Cell Therapy Introduction and Practical Guide to Use in Small Animal Practice 6650-0018-002 What Do Stem Cells Do? 10 million cells die in your body every minute of every day. Your own stem cells replace them so you can continue living. This is what stem cells do for a living. 6650-0018-002 What are Stem Cells? Stem Cells are Primitive cells present in almost every tissue: • • • Self Renewing Able to become different tissue types Trophic Factories – Growth Factors 6650-0018-002 Embryonic vs Adult Stem Cells Stem Cells from Embryos • • • Intended to form whole animal - not for repair Can form tumors – UNPREDICTABLE Maybe someday Adult Stem Cells – many sources • • • Intended for self repair Do not form tumors when injected Now Gruen L and Grabel L, Stem Cell 2006;24;2162-2169. 6650-0018-002 Enabling Innovation Dr. Bill Futrell, et al – Univ of Pittsburgh 1998 “Discovered true stem cells in fat that could create new tissues like bone and cartilage” Stem Cells from fat Extracted can become bone in the lab Fix fractures 6650-0018-002 Why Adipose as Stem Cell Source? High healing cell count – No culturing required 1000X stem cell concentration as bone marrow Family of healing cells - heterogeneous Rapid, Easy to access Over 1700 peer reviewed papers published 6650-0018-002 What Cells Do We Use?1 6650-0018-002 Mechanisms of Repair • Trophic support - growth factors and cytokines • Anti-inflammatory • Differentiation into tissue • Homing to injury site • Immune System Modulation 6650-0018-002 The Injury Response Cascade Magnitude Inflammation “Regeneration” Fibrosis QUICK FIX Acute Injury Time Scar Complete Courtesy, A Caplan, Case Western Reserve 6650-0018-002 Magnitude Stem Cells in Injury Response “Regeneration” Inflammation Fibrosis Time Acute Injury Stem Cells Scar Reduced Courtesy, A Caplan, Case Western Reserve Roles / Functions “Stem cells are injury-specific, perfectly choreographed pharmaceutical factories” Dr. Arnold Caplan Case Western Reserve Influence by injury micro-environment 6650-0018-002 Stem Cells and Joint Therapy Mechanisms Chondrogenesis1 - new cartilage formation Lubricin2 - lubricate joint, improve range of motion IRAP Secretion3 - blocks IL-1 inflammation mediator Decrease Inflammation4 - reduce pain and swelling 1 2 3 4 Wei et al, Cytotherapy, 2007 Lee et al, BBRC, 2008 Ortiz et al, PNAS 2007 Tholpady, Plast Surg, 2006 6650-0018-002 Evidence-based Cell Therapy DATA TYPE AVAILABLE Canine Osteoarthritis Canine Tendon and Ligament In-vitro (lab bench) X X Lab Animal X X Case Studies X X Retrospective Studies X X Non-Random, Prospective X X Randomized, Controlled X (equine) Human Clinical Studies X X STATUS Supported Supported 6650-0018-002 Rabbit Osteochondral Defect Repair Model Nathan et al, “Cell-based therapy in the repair of osteochondral defects: A novel use for adipose tissue” Tissue Engineering, 2003. 6650-0018-002 Elbow Dysplasia - DJD Annie – 9 YO Chronic elbow dysplasia – non-NSAID controlled pain Stem Cell Therapy at Day 0 and 14.
