STUDY ON CHEMOSENSITIVITY OF COLONY FORMING CELLS

[In vitro chemosensitivity test by human tumor colony forming assay].

In vitro chemosensitivity of urological cancers was assessed by a human tumor colony forming assay (HTCA) and a 3H-thymidine incorporation assay. Primary tumor cells from 160 of 253 (63%) urological cancers showed adequate colony growth (greater than 30 colonies per well), and there was a 57% true positive and 100% true negative rate for predicting clinical response of anticancer agents. On the...

The effect of corticotropin on mouse spleen colony-forming cells.

Several investigators have reported a retechnique. There was a marked decrease duction in the number of colony-forming in spleen CPU in these mice when cornunitsjCFU) in the sple.ns of mice exposed pared with control animals, but marrow to hypoxia and have postulated that this is CPU were not reduced. These tesults mdis.condary to a direct toxic effect of hypoxcafe that part of the effect of hy...

Hematopoietic colony-forming cells derived from human embryonic stem cells.

Human embryonic stem (ES) cells are undifferentiated, pluripotent cells that can be maintained indefinitely in culture. Here we demonstrate that human ES cells differentiate to hematopoietic precursor cells when cocultured with the murine bone marrow cell line S17 or the yolk sac endothelial cell line C166. This hematopoietic differentiation requires fetal bovine serum, but no other exogenous c...
