Abstract:
Proliferation of the Ishikawa human endometrial adenocarcinoma cell line is under the concerted control of oestrogen and progesterone. Here we demonstrate that Ishikawa cells express colony stimulating factor-1 (CSF-1), CSF-1 receptor mRNA and are growth stimulated by CSF-1 treatment. An early event associated with CSF-1 treatment is the induction of lipocortin II synthesis, a protein whose expression is also under oestrogen and progesterone control. However, neither CSF-1 or CSF-1 receptor mRNA appear to be modulated by oestrogen or progesterone.
