Endometrial hyperplasia is a proliferation (excessive growth) or thickening of the endometrium which may involve part or all of the endometrium.
There is no significant necrosis (cell death) or vascular proliferation (increased blood vessel growth - cancerous tumours create extra blood vessels).
Grade II - slow-growing tumours with more rapidly dividing cells.
Polycythemia vera is a rare, chronic disorder involving the overproduction of blood cells in the bone marrow (myeloproliferation).
The rapid proliferation of abnormal myeloid WBCs and their reduced ability to mature and to die normally results in their accumulation in the bone marrow.

A hematopoietic growth factor which promotes proliferation and maturation of neutrophil granulocytes.
What is a beryllium lymphocyte proliferation test (BeLPT)?
The beryllium lymphocyte proliferation test (BeLPT) is a test that measures beryllium sensitization, which is the immune system's reaction to beryllium.
New cells are made by a process called cellular proliferation. Before dividing, a cell makes a new set of chromosomes out of Deoxyribonucleic Acid (DNA) so that there are two copies of the chromosomes in the cell.
These are biological substances that exert their influence by causing cellular growth and proliferation.

To identify certain forms of cell proliferation as neoplastic, it is necessary to demonstrate that the cell population is genetically identical to a single progenitor cell (clonality).
Such damage inhibits skin cell proliferation and reduces psoriasis plaque formation. PUVA employs a combination of a psoralen drug and UVA radiation. Forms of psoralen include methoxsalen, 8-methoxypsoralen (8-MOP), or bergapten (5-MOP).
The naevus cells form a row along the dermoepidermal junction (called lentiginous proliferation), with or without naevus cells in nests (called theques).
These theques are often irregular in size and shape and may 'bridge' or join together.
Most moles are simply the result of a harmless proliferation of the pigment cells within the deeper layer of the skin. A few of these moles, called congenital melanonaevi, are usually present at birth.
A proliferation of abnormal gamma globulin, or paraproteins, is likewise a sign of immune malfunction. Diseases of the gamma globulin such as this are called gammopathy.
