α‐L‐Fucosidase of human skin fibroblasts and amniotic fluid cells in tissue culture

Cultured amniotic fluid cells had a higher level of alpha-L-fucosidase than skin fibroblasts. The early passages of amniotic fluid cells had a higher activity than later passages, whilst skin fibroblast activity was unrelated to passage. For both cell types alpha-L-fucosidase activity fell on subculture, rising again at confluency.
