| 背景描述 |
HS-27A is a fibroblast cell line that was isolated in (year from History) from the stroma of a 30-year-old White male donor. HS-27A is a subclone of HS-27.HS-27A forms large flattened polygonal shaped cells that exemplify "blanket" cells and maintain numerous intercellular contacts with neighboring cells. Unlike HS-5, HS-27A secretes low levels of growth factors and does not support proliferation of isolated progenitor cells in cocultures. HS-27A expresses relatively high levels of vascular cell adhesion molecule 1 (VCAM-1). |
