 [ne″o-jen´ĕ-sis]
tissue regeneration. adj., adj neogenet´ic.

re·gen·er·a·tion

(rē'jen-ĕr-ā'shŭn),
1. Reproduction or reconstitution of a lost or injured part. Synonym(s): neogenesis
2. A form of asexual reproduction; for example, when a worm is divided into two or more parts, each segment regenerates into a new individual.
[L. regeneratio (see regenerate)]

During the development of the pancreas as well as subsequently, beta-cell apoptosis is normal, although this loss is compensated by neogenesis from preexisting beta-cells or from trans-differentiation of acinar cells (56).
In the meantime, VEGF that is secreted by tumor cells may, through the paracrine pattern, induce the neogenesis of blood vessels and lymphatic endothelial cells as well as promote the proliferation of tumor cells.15

In another attempt, Kodama et al transplanted pancreatic cell ontogeny within ESCs into the renal capsule of STZ induced diabetic mice which resulted in pancreatogenesis in situ or beta cell neogenesis. Twenty-one days post transplantation, PDX-1+ pancreatic foci appeared in the renal capsule, which expressed exocrine enzymes (amylase) and endocrine hormones (insulin, glucagon, and somatostatin).

Mesenchymal stem cell, one of the adult stem cells, is used a lot for neogenesis, and stem cell research institute of STC Life used stem cells separated from umbilical cord of fetus.
Mature rat [beta]-cells have a life span of a few weeks and are replaced by the replication of pre-existing [beta]-cells or by the differentiation and proliferation of precursor cells present in the pancreatic ducts (Wang et al., 1995) It has been strongly suggested that during postnatal life, Pdx-1 may also be essential for the neogenesis of endocrine cells through differentiation from precursor cells that reside among the cells lining the pancreatic ducts (Bouwens and Kloppel, 1996).
Histopathologic evaluation reveals patchy, organized (lymphoid neogenesis) interstitial inflammation, intermittent interstitial fibrosis and associated parenchymal atrophy (atrophy of adnexal structures, thinning of epidermis), graft vascular disease (concentric fibrointimal hyperplasia of arteries), destruction of epithelial lined conduits, and destruction and atrophy of organ-associated lymphoid tissue and lymphatics.

Platelets release growth factors which have the following effects: Cell growth, regeneration and repair of blood vessels, collagen production, tissue repair, hyaluronic acid production, growth and new generation of vascular endothelial cells, promotion of endothelial cells , promotion of epithelial cell growth, angiogenesis , promotion of wound healing (ie: chronic pressure wounds), growth and neogenesis of epithelial and vascular endothelial cells.
The accordion technique of Ilizarov is based on the observation that the fibrous tissue surrounding the bone ends can be transformed into tissues capable of neogenesis and was necessarily adopted in each case.
