| Age： | 30 years |
| Gender： | male |
| Ethnicity： | Caucasian |
| Storage Conditions： | liquid nitrogen vapor phase |
| Derivation： | 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. |
| Clinical Data： | 30 years Caucasian male |
| Antigen Expression： | vascular cell adhesion molecule 1 (CD106, VCAM-1) |
| Comments： | HS-27A is a subclone of HS-27. One of these cell lines HS-27A (CRL-2496) has been deposited in the ATCCs general collection. 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. 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). HS-27A supports the formation of "cobblestone" areas by isolated cells positive for CD34 but low for CD38. |
| Complete Growth Medium： | The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, ATCC 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum (ATCC 30-2020) to a final concentration of 10%.
|
| Subculturing： | Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
Subculture Ratio: 1:4 to 1:5 Medium Renewal: 2 to 3 times a week.
Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 10 in Culture of Animal Cells, a manual of Basic Technique by R. Ian Freshney, 3rd edition, published by Alan R. Liss, N.Y., 1994.
