Paracrine Factors of Mesenchymal Stem Cells Recruit Macrophages and Endothelial Lineage Cells and Enhance Wound Healing: ”
by Liwen Chen, Edward E. Tredget, Philip Y. G. Wu, Yaojiong Wu
Bone marrow derived mesenchymal stem cells (BM-MSCs) have been shown to enhance wound healing; however, the mechanisms involved are barely understood. In this study, we examined paracrine factors [...]

In Vivo Isolation and Characterization of Stem Cells with Diverse Phenotypes Using Growth Factor Impregnated Biomatrices: ”
by Annalisa Grimaldi, Cristiano Bianchi, Gabriella Greco, Gianluca Tettamanti, Douglas M. Noonan, Roberto Valvassori, Magda de Eguileor
Background
The stimulation to differentiate into specific cell types for somatic stem cells is largely due to a series of internal and external signals [...]

GPCR Genes Are Preferentially Retained after Whole Genome Duplication: ”
by Jenia Semyonov, Jae-Il Park, Chia Lin Chang, Sheau Yu Teddy Hsu
One of the most interesting questions in biology is whether certain pathways have been favored during evolution, and if so, what properties could cause such a preference. Due to the lack of experimental evidence, whether [...]

Ecological Niche Dimensionality and the Evolutionary Diversification of Stick Insects: ”
by Patrik Nosil, Cristina P. Sandoval
The degree of phenotypic divergence and reproductive isolation between taxon pairs can vary quantitatively, and often increases as evolutionary divergence proceeds through various stages, from polymorphism to population differentiation, ecotype and race formation, [...]

Anesthetics Impact the Resolution of Inflammation: ”
by Nan Chiang, Jan M. Schwab, Gabrielle Fredman, Kie Kasuga, Simon Gelman, Charles N. Serhan
Background
Local and volatile anesthetics are widely used for surgery. It is not known whether anesthetics impinge on the orchestrated events in spontaneous resolution of acute inflammation. Here we investigated whether a commonly used local anesthetic [...]

Hippocampus Shape Analysis and Late-Life Depression: ”
by Zheen Zhao, Warren D. Taylor, Martin Styner, David C. Steffens, K. Ranga R. Krishnan, James R. MacFall
Major depression in the elderly is associated with brain structural changes and vascular lesions. Changes in the subcortical regions of the limbic system have also been noted. Studies examining hippocampus volumetric differences [...]
