Abstract

A new tumor cell line has been established from a malignant pleural effusion in a 28-yr-old female patient with a primary alveolar rhabdomyosarcoma of the left buttock. The in vitro and in vivo growth characteristics, morphologic features, abnormal karyotype, and immunohistochemical staining pattern indicate that this cell line is comprised of primitive malignant mesenchymal cells derived from a human rhabdomyosarcoma. Receptor studies done on tumors grown in male athymic mice revealed a single class of high affinity saturable cytoplasmic estrogen receptor (Bmax 2.6 fm/mg cytosol protein, Kd 0.34 nM). Likewise, sucrose density gradient analysis demonstrated specific low-capacity, high-affinity estradiol binding predominately in the 8S region. Cell growth in monolayer culture and on soft agar in the presence of estradiol was inhibited by pharmacologic concentrations of estradiol in a dose-responsive manner compared with control. We describe a newly characterized malignant mesenchymal cell line derived from an alveolar rhabdomyosarcoma that is inhibited by pharmacologic doses of estradiol in vitro. These findings suggest further investigation into the mechanism(s) of this estrogen-induced inhibition in rhabdomyosarcomas.
