Clean Semiprime f-Rings with Bounded Inversion
An element in a ring is called clean if it may be written as a sum of a unit and idempotent. The ring itself is called clean if every element is clean. Recently, Anderson and Camillo (Anderson, D. D., Camillo, V. (2002). Commutative rings whose elements are a sum of a unit and an idempotent. Comm. Algebra 30(7):3327–3336) has shown that for commutative rings every von-Neumann regular ring as we...
متن کاملImportance of Floating Chondrons in Cartilage Tissue Engineering
BACKGROUND Dedifferentiation of chondrocytes remains a major problem for cartilage tissue engineering. Chondrocytes loss differentiated phenotype in in vitro culture that is undesired for repair strategies. The chondrocyte is surrounded by a pericellular matrix (PCM), together forming the chondron. PCM has a positive effect on the maintenance of chondrocyte phenotype during culture in compar...
متن کاملTissue engineering of cartilage
The main goal of tissue engineering is to create artificial constructs that could repair or simply replace lost or damaged tissue. Common tissue engineering strategies involve the extraction of cells from a small biopsy of tissue for in vitro expansion. This culture can be carried out in a three dimensional (3D) scaffold that allows and induces the formation of new tissue after implantation. Fu...
متن کاملTwo modes of action by which Xenopus hairy2b establishes tissue demarcation in the Spemann-Mangold organizer.
The Hairy and Enhancer-of-Split (HES) family of transcriptional repressors plays important roles in pattern formation during development throughout the animal kingdom. Generally, HES proteins repress the expression of genes specific for neighboring tissues to maintain the nature of cells expressing HES proteins, resulting in pattern formation. Xhairy2b, a Xenopus HES, establishes the prospectiv...
متن کاملDesigning of Human Cartilage Tissue, by Differentiation of Adipose-Derived Stem Cells With BMP-6 in Alginate Scaffold
Purpose: In the present study the effect of BMP-6 was investigated on chondrogenesis of adiposederived stem cells. Materials and Methods: Mesenchymal stem cells derived from subcutaneous adipose tissue were cultured on alginate scaffold to induce chondrogenesis in experimental group, with chondrogenic medium having BMP-6 growth factor for 3 weeks. In control group medium without BMP-6 was appli...
