Abstract

Analysis of MM14 mouse myoblasts demonstrates that terminal differentiation is repressed by pure preparations of both acidic and basic fibroblast growth factor (FGF). Basic FGF is approximately 30-fold more potent than acidic FGF and it exhibits half maximal activity in clonal assays at 0.03 ng/ml (2 pM). FGF repression occurs only during the G1 phase of the cell cycle by a mechanism that appears to be independent of ongoing cell proliferation. When exponentially growing myoblasts are deprived of FGF, cells become postmitotic within 2-3 h, express muscle-specific proteins within 6-7 h, and commence fusion within 12-14 h. Although expression of these three terminal differentiation phenotypes occurs at different times, all are initiated by a single regulatory "commitment" event in G1. The entire population commits to terminal differentiation within 12.5 h of FGF removal as all cells complete the cell cycle and move into G1. Differentiation does not require a new round of DNA synthesis. Comparison of MM14 behavior with other myoblast types suggests a general model for skeletal muscle development in which specific growth factors serve the dual role of stimulating myoblast proliferation and directly repressing terminal differentiation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
