These are the results of between two and four experiments. ^Stromal clones derived from E10 tissue. All other stromal clones derived from E11 tissues. †Stromal clones derived from BL1b transgenic embryos. All other stromal clones are derived from tsA58* transgenic embryos. Culture supernatants were collected from non-irradiated cells.
