What condition is associated with a homogeneous population of a single cell type?

Neoplasia is characterized by the abnormal proliferation of cells, resulting in a homogeneous population of cells derived from a single cell type. This condition indicates a growth that is often autonomous and can be benign or malignant. In neoplasia, the cellular characteristics are distinct and resemble one another, showing uniformity in size, shape, and nuclear features. This uniformity contrasts with other conditions where cell populations may be heterogeneous or a mix of different cell types.

In the context of the other options, inflammation typically involves a diverse array of cell types, including lymphocytes, neutrophils, and macrophages, resulting in a mixed cell population. Necrosis is associated with cell death and damage, which can attract different cell types for repair, further reflecting a heterogeneous environment. Dysplasia indicates abnormal cell growth and changes in tissue architecture that lead to a varied mix of cell sizes and shapes, rather than a homogeneous population. Thus, neoplasia is the key condition linked to a single, uniform cell type.
