Background
While suggested to be effective in tissue regeneration, the effects of horizontal platelet‐rich fibrin (H‐PRF) bone block in sinus augmentation have not been verified in an animal model.
Methods
A total of 12 male New Zealand white rabbits that underwent sinus augmentation were divided into two groups: deproteinized bovine bone mineral (DBBM) only and H‐PRF bone block. H‐PRF was prepared...
Angiogenesis is critical in tissue engineering and regenerative medicine. Once initiated, outgrowing capillaries are spearheaded by specialized endothelial cells (ECs) termed tip cells. Specification of tip cells from ECs during angiogenesis is greatly influenced by the surrounding extracellular matrix (ECM). However, the crosstalk between ECs and the ECM in tip cell specification is poorly understood...
Objective: To study the expression of angiopoietin-1 (Ang-1), angiopoietin-2 (Ang-2) and the angiopoietin receptor (Tie-2) in colorectal cancer tissue, and analyze the correlation between their expression levels in colorectal cancer tissue and the histological differentiation of colorectal cancer; and to discuss their roles in the progression of colorectal cancer to provide new targets for the clinical...
