Transforming growth factor beta 1 is an inducer of erythroid differentiation

Normal human bone marrow cells, highly enriched for burst-forming units-erythroid (BFU-E), were cultured in serum-free medium, in the presence and absence of various factors, to investigate the mechanisms involved in regulating erythroid differentiation. In cultures containing interleukin 3 (IL-3), Steel factor (SF), and erythropoietin (Ep), benzidine-positive erythroblasts first became detecta...

Basic fibroblast growth factor antagonizes transforming growth factor beta-mediated erythroid differentiation in K562 cells.

Basic fibroblast growth factor (bFGF) and transforming growth factor-beta 1 (TGF-beta) have both been shown to act on hematopoietic progenitor cells. bFGF is a hematopoietic cytokine that acts on progenitor cells in concert with other cytokines to promote their proliferation. TGF-beta induces erythroid differentiation in K562 cells. To determine whether bFGF might act on progenitor cells by ant...

Plasma levels of Transforming Growth Factor Beta in HIV-1 patients with oral candidiasis

Background and Purpose: TGF-β is a potent regulator and suppressor of the immune system and overproduction of this cytokine may contribute to immunosuppression in HIV-infected patients. Increasing population of immunosuppressed patients has resulted in increasingly frequent of fungal infections, including oral candidiasis. The aim of this study was to evaluate the plasma levels of TGF-&bet...

The Role of Transforming Growth Factor Beta 1 (TGFβ1) in Nasal and Paranasal Sinuses Polyposis

  Background and Objectives: Nasal polyposis is a diseases resulting from complex pathogenetic mechanisms. Some studies showed that TGFβ1 had significant role in this pathogenesis. In this study, we investigated the roe of cytokines and mediators in polyp development. Material and Methods: In this case- control study, healthy nasal mucosal samples were obtained from 24 peopl...

Regulation of myogenic differentiation by type beta transforming growth factor

Type beta transforming growth factor (TGF beta) has been shown to be both a positive and negative regulator of cellular proliferation and differentiation. The effects of TGF beta also are cell-type specific and appear to be modulated by other growth factors. In the present study, we examined the potential of TGF beta for control of myogenic differentiation. In mouse C-2 myoblasts, TGF beta inhi...
