Neuropeptides as growth regulators
British Medical Bulletin, 1989The classical role of neuropeptides as fast-acting neurohumoral signallers has recently been challenged by the discovery that many neuropeptides are also growth factors stimulating slow-acting mitogenesis. Their mechanisms of action have been studied in cell culture, and their cell-surface receptors have been characterized pharmacologically using ...

Growth Factors and Regulation of Cell Growth
Annual Review of Medicine, 1982A new class of polypeptide hormones known collectively as growth factors has been identified. These polypeptides are able to stimulate DNA synthesis and mitosis of cells cultured in vitro. Growth factors have been isolated from several sources, including platelets, submaxillary glands, pituitary, brain, and medium conditioned by cells grown in vitro ...

Physiological Reviews, 1986
The liver is a conditional renewal system, which in the adult organism undergoes minimal cell production and/or cell renewal. However, a reduction in liver cell mass, because of either actual cell loss or cell atrophy, evokes a rapid regenerative response tailored to replace the lost tissue.

Transforming Growth Factor Regulation of Keratinocyte Growth
1993Transforming growth factors (TGF) were originally defined by their ability to induce morphologic transformation in monolayer culture and stimulate soft agar growth of rodent fibroblast cell lines (DeLarco and Todaro 1978; Moses et al. 1981; Roberts et al. 1981). Early studies with TGF indicated that they may play a role in neoplastic transformation and

Growth regulation by transforming growth factor-β
1993The name transforming growth factor-s (TGF-s) has come to represent a family of highly homologous polypeptides with a wide range of biological activities. The first member of this gene family was identified nearly a decade ago as one of two essential factors, called TGF-α and TGF-s present in the conditioned medium of a murine sarcoma virus-transformed

Publisher Summary This chapter discusses the mechanisms regulating cellular growth. Many of the hormones that control the activity of one or another endocrine gland also promote the growth of that target gland. Hormones, such as insulin and growth hormone, affect many different tissues.

Growth regulator chemicals have been defined as organic compounds, other than nutrients, which, in small amounts, promote, inhibit, or otherwise modify any physiological process in plants. Control of growth in horticulture is usually practiced through temperature, water, feeding, photoperiod, and pruning. Chemical growth regulators give us one more set
