title: Observation and quantitative analysis of rat bone marrow stromal cells cultured in vitro on newly formed transparent beta-tricalcium phosphate.
abstract: To observe living cell morphology on ceramics by light microscopy, we fabricated a new material-transparent beta - tricalcium phosphate (t-beta TCP) ceramic-for the purpose of serving as a tissue culture substrate. Bone marrow stromal cells (BMSCs) were obtained from rat femora and cultured on both t-beta TCP ceramic disks and culture grade polystyrene (PS) dishes in an osteogenic medium. After 1 day of culture, cell attachment and spreading on both the t-beta TCP and PS substrata were equally and clearly detected by ordinary light microscopy. After 14 days of culture, extensive cell growth, alkaline phosphatase (ALP) staining, and bone mineral deposition could be detected on both substrata. In addition, quantitative biochemical analyses revealed high DNA content, ALP activity, and osteocalcin content of these cultures. This experiment is significant in that all of the results were similarly observed on both the t-beta TCP and PS substrata, indicating the excellent properties of beta TCP ceramics for BMSCs culture towards osteogenic differentiation.
