The effects of exogenously added transforming growth factor (TGF alpha and TGF beta on the growth of BALB/MK cells were examined. TGF alpha supplanted the epidermal growth factor (EGF) requirement in these cells. In contrast, TGF beta reversibly inhibited the growth of BALB/MK cells by abrogating the stimulatory actions of EGF or TGF alpha. The inhibitory effects of TGF beta appeared to be medi...

Nonneoplastic cell lines are unable to grow in soft agar. However, concomitant treatment of these cells with epidermal growth factor and transforming growth factor ßconfers upon them anchorage independence. Since articular chondrocytes are unique as normal diploid cells that do have the capability of growing in soft agar, we tested whether transforming growth factor ßand epidermal growth fact...

To explore bidirectional regulatory interactions between interferons and autocrine polypeptide factors, we examined the modulation of expression of transforming growth factor-a and 2’,5’-oligoadenylate synthetase activity in A431 epidermoid carcinoma cells after treatment with interferon-y and transforming growth factor-a. Treatment of A431 cells with interferon-y increased steady state levels ...

1. In order to assess potential abnormalities in the control of mucosal proliferation, 30 patients with Barrett's oesophagus were studied in order to evaluate the presence and distribution of epidermal growth factor, transforming growth factor-alpha and epidermal growth factor receptor to determine the Ki-67 labelling index in the affected oesophageal mucosa. Serial sections were analysed immun...
