		Antigen Expression:	vascular cell adhesion molecule 1 (CD106, VCAM-1)
	
	
		Age:	30 years
	
	
		Gender:	male
	
	
		Ethnicity:	Caucasian
	
	
		Comments:	Long term bone marrow cells were transformed with the amphotropic retrovirus vector LXSN16E6E7 in the presence of polybrene.
	
	
		Twenty-seven immortalized clones designed HS-1 to HS-27 were isolated.
	
	
		HS-27A is a subclone of HS-27.
	
	
		One of these cell lines HS-27A (CRL-2496) has been deposited in the ATCC 's general collection. HS-27A細胞One cell line (HS-5) has been deposited in the Patent Depository (CRL-11882).
	
	
		HS-27A forms large flattened polygonal shaped cells that exemplify "blanket" cells and maintain numerous intercellular contacts with neighboring cells. [44213]
	
	
		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). [40180]
	
	
		HS-27A supports the formation of "cobblestone" areas by isolated cells positive for CD34 but low for CD38. [40180]
	
	
		Propagation:	ATCC complete growth medium: The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
	
	
		Temperature: 37.0°C
	
	
		Subculturing:	Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:5 is recommended
