Summary. The sensitivity of populations of human granulocyte precursors to factors with colony stimulating activity (CSA) was assessed in agar culture in vitro. The mean threshold of stimulation was estimated by analysis of dose‐response curves of clone growth against concentration of CSA.

AbstractThe fine structure of testicular interstitial cells from mice submitted to different experimental conditions is described. Following treatment with methallibure (I.C.I. 33,828; 1‐α‐methylallylthiocarbamoyl‐2‐methylthiocarbamoylhydrazine), a selective inhibitor of hypophyseal gonadotropic activity, interstitial cells acquire a quiescent ...

Germ Cell Stimulation of Sertoli Cell Protein Phosphorylation*
Endocrinology, 1987Cultures of Sertoli cells were treated with freshly isolated, intact germ cells to determine if germ cells were capable of influencing Sertoli cell function. By using two-dimensional polyacrylamide gel electrophoresis and autoradiography, germ cells were found to increase several-fold the incorporation of [32P]orthophosphate into two phosphoproteins ...

Stimulation of Schwann cells by infrared pulsed stimulation
Optical Techniques in Neurosurgery, Neurophotonics, and Optogenetics, 2021Schwann cells are the most abundant glial cell in the peripheral nervous system. Apart from their important role on axonal myelination they exert a key role on the regulation of axonal excitability and metabolism, nerve repair, immunological response and pain sensation.

B-cell stimulation by T-cell-secreted proteoglycan
Cellular Immunology, 1987We have further characterized a recently described B-cell stimulatory factor that contains chondroitin sulfate proteoglycan and 70- to 75-kDa protein, both of which are secreted by T cells and coisolate (T-cell proteoglycan fraction, T-PGF). Using T-PGF isolated from a T-cell hybridoma (T14), it was observed that the association between B-cell ...

Cell Response to Surface Stimulation
Nature New Biology, 1972It has been known for some time that in normal cells growing in culture a relationship exists between cell density and mitotic index1. At a certain saturation density contact inhibition of growth occurs2–4; DNA synthesis decreases and cell division ceases or is drastically reduced.

Stimulated raman scattering cell
Review of Scientific Instruments, 1980Construction of an apertured Dewar cell designed for transforming the 1.06 μm Q-switched pulses of a Nd+3 glass laser by stimulated Raman scattering in liquid N2 or O2 is described. Performance data for the 1.06 μm to 1.4 μm conversion in N2 are given.

Mechanisms of thrombin‐stimulated cell division
Journal of Supramolecular Structure, 1979AbstractAddition of highly purified thrombin t o cultures of several kinds of nondividing fibroblasts brings about cell division. This stimulation occurs in serum‐free medium, permitting studies on its mechanism under chemically defined conditions. Previous studies have shown that action of thrombin a t the cell surface is sufficient to cause cell ...

Angiotensin stimulation of adrenal fasciculata cells
Archives of Biochemistry and Biophysics, 1988In this paper we provide evidence to show that the pathways by which adrenocorticotropic hormone (ACTH) and angiotensin II (AII) stimulate steroidogenesis in bovine fasciculata cells are only partially independent. Both hormones have the same intrinsic activity but a 500-fold higher dose of AII is required to achieve 50% stimulation of steroidogenesis.
