You could take peripheral blood and stimulate it with Concanavalin A
(I used 5 micrograms Con A/ml with a cell concentration of 5 x
10^6/ml). After 48 hours, spin the culture to remove cells, add
alpha-methyl mannoside to bind residual Con A, and filter through a
0.22 micron filter. Use this conditioned media at a 10% final
concentration with your cultured cells. I have had very good luck
with this source of growth factors.
