Development of sensitivity to 50 mmK+
| Age in culture (DIV) | Control | 10 ng/ml bFGF |
|---|---|---|
| 0.5 | 17/51 (33.3%) | |
| 2 | 20 /27 (74.1%) | 23 /31 (74.2%) |
| 3 | 34 /39 (87.2%) | 42 /51 (82.4%) |
| 4 | 48 /50 (98.0%) | 36 /36 (100%) |
Values shown are the numbers of cells that showed detectable [Ca2+]i rise in response to 50 mmK+ versus the numbers of cells examined. Percentages of responding cells are given in parentheses. bFGF was added to cultures at 0.5 DIV.
