proliférante

Proliférante is a term used in biology and medicine to describe something that promotes or causes proliferation—the rapid increase in the number of cells or tissues. In French, proliferer means to multiply, and proliférant (masc.) or proliférante (fem.) are the related present participle forms that describe an agent, signal, or condition with a proliferative effect. The word may also appear as a noun in some contexts, though this usage is less common.

In biology and medicine, prolifération is a central concept, and proliférants are factors or stimuli that induce cell division and tissue growth. Common examples include growth factors and certain hormones or cytokines that activate signaling pathways leading to cell cycle progression. Proliferative signals are essential for development and wound healing but can contribute to pathological conditions when they become dysregulated.

In pathology, the term is often used descriptively. A tissue or region may undergo a proliférante reaction, characterized by increased cell proliferation seen in processes such as hyperplasia, tissue repair, or, in some cases, tumor growth. The term does not denote a diagnosis by itself; rather, it describes a proliferative tendency or effect observed in a given context.

Etymology traces proliférante to the Latin prolifferāre, via French proliférer, with the adjectival form denoting an agent or condition that promotes proliferation. Related concepts include proliferation, hyperplasia, and growth factors. Overall, proliférante is a descriptive term used to indicate a propensity or action that increases cell or tissue numbers.
