Thymocyte proliferative response to HK-1 and SubP. Single-cell suspensions were made from adult or day-15 fetal thymi and cultured with or without HK-1 or SubP in the presence of suboptimal concentrations of IL-7 and SCF. The concentrations of HK-1 and SubP are indicated in brackets in micromolars. Values of counts per minute (cpm) are the mean of triplicate samples. (A) Proliferation of adult thymocytes. There were 4 × 105 cells plated into each well. (B) Proliferation of day-15 fetal thymocytes. There were 4 × 104 cells plated into each well.
