Abstract (original English)
Mesenchymal stem cells (MSCs) have potential in orthopaedic applications as they are able to differentiate into bone and cartilage. These cells can be isolated from a variety of adult tissues. Three sources that are relevant for orthopaedic applications are bone marrow, periosteum and adipose tissue. The purpose of the present study was to compare the growth kinetics and colony forming potency of rat MSCs from these sources. Bone marrow from the femur periosteum from the femoral diaphysis and adipose tissue from the inguinal area of Wistar rats were harvested for MSC isolation. The cells from 2nd-4th passage from primary culture were selected for study of their growth curves, population doubling time and colony forming ability using the percentage of colony forming units and colony forming area as the outcome measure. The isolated cells from these 3 sources were capable of osteogenesis, chondrogenesis and adipogenesis. The growth kinetics were compared using the growth curve and the population doubling time (PDT): bone marrow derived cells (PDT = 3.99 days, SD = 1.19) and periosteum derived cells (PDT = 3.55 days, SD = 1.21) had faster growth kinetics than adipose derived cells (PDT = 4.65 days, SD = 1.53). The percentage of colony forming units and the colony forming area from bone marrow derived cells (% colony forming unit = 8.58, SD = 1.35 and % colony forming area = 25.12,
