pubmed:abstractText |
The polypeptides PDGF, TGF alpha, and EGF have previously been shown by others to stimulate proliferation of fibroblasts and keratinocytes in the process of wound healing. Here we demonstrate that extracellular ATP, ADP or AMPPNP caused synergistic enhancement of DNA synthesis in 3T6 mouse fibroblasts and BALB/MK keratinocytes when combined with any of the above polypeptides. TGF beta showed synergistic stimulation with ATP in fibroblasts but it inhibited keratinocytes. ATP acted as a mitogen for NIE-115 neuroblastoma cultures. In 3T6 cells, ATP stimulated thymidine incorporation in combination with carbachol or norepinephrine. The effect of carbachol was sensitive to atropine. We suggest that extracellular ATP and ADP may play a physiological role in wound healing and as a mitogenic neurotransmitter in the nervous system.
