The phrase "a normal proliferation" is correct and usable in written English.
It can be used in contexts discussing the typical increase or growth of something, often in scientific or biological discussions.
Example: "In healthy ecosystems, a normal proliferation of species contributes to biodiversity and stability."
Alternatives: "a typical increase" or "a standard growth".
Despite a high level of c-Myc and a low NMD, Smg6-null ESCs exhibit a normal proliferation and apoptotic response and are devoid of transformation.
This is because OXA, TPM, and LTG may alter bone microstructure and bone turnover rate but maintain an adequate bone mass, leading to a normal statural growth rate in vivo and a normal proliferation of bone cells in vitro.
Finally, sustained proliferative signaling may well be the result of perpetual activation of the intracellular signaling chain independent of growth factors or receptors (e.g. mutated ras (257) or truncated src (258) are intermediaries of a normal proliferation signaling chain responsible for sustained proliferation).
However, at 1.5 mg ml-1 a complete normal proliferation pattern was obtained.
In contrast to proliferation-inhibited cells expressing solely Smad7, cells expressing E2F-1 and Smad7 exhibited an almost normal proliferation with nontransformed phenotypes (Fig. 6B).
PLC restored an almost normal proliferation rate of colonocytes, as documented from the reduction in BrdU+ cryptic cells (P<0.01 vs. TNBS alone).
In contrast, release of LNCaP cells from mifepristone treatment did not result in a return to normal proliferation.
In this context, the observed aneuploidization may be indicative of a defect in normal proliferation or growth control in the pretransformed or early transformed sarcoma cells of origin.
While the successful generation of gene knockouts for RabX1 and RabX2 indicate that these genes are not essential, we investigated a possible role in normal proliferation of trypanosomes by analyzing the growth of knockout cells in in vitro culture.
Estrogen plays an important role in normal proliferation of the mammary epithelium and participates in progression to a neoplastic state.
Wnts are secreted cysteine-rich glycoproteins that act as short-range ligands to locally activate receptor-mediated signalling pathways, and they have been shown to be an essential requirement for normal proliferation and differentiation of the mucosa of the small intestine and colon [35].
