[Cell-biology] fibroblast cells

[Natalia Beloukhina]

I am working with human fibroblast cells, specifically Det 551 and I am
finding them to be really slow growing.  Does anyone have a suggestion as to
other normal human fibroblasts that grow well and fast in F10 medium and
have a relatively long lifespan, the current ones are quoted as 25 serial
passages from the tissue of origin.
