Cardiac progenitor cell-derived extracellular vesicles promote angiogenesis through both associated- and co-isolated proteins.

Extracellular vesicles (EVs) are cell-derived lipid bilayer-enclosed particles that play a role in intercellular communication. Cardiac progenitor cell (CPC)-derived EVs have been shown to protect the myocardium against ischemia-reperfusion injury via pro-angiogenic effects. However, the mechanisms underlying CPC-EV-induced angiogenesis remain elusive.

Towards integrated paediatric services in the Netherlands: a survey of views and policies on collaboration in the care for children with cerebral palsy.

Aim: Worldwide, family-centred and co-ordinated care are seen as the two most desirable and effective methods of paediatric care delivery. This study outlines current views on how team collaboration comprising professionals in paediatric rehabilitation and special education and the parents of children with disabilities should be organized, and analyses the policies of five paediatric rehabilitation settings associated with the care of 44 children with cerebral palsy (CP) in the Netherlands.

Methods: For an overview of current ideas on collaboration, written statements of professional associations in Dutch paediatric rehabilitation were examined.

A review of salient elements defining team collaboration in paediatric rehabilitation.

Objective: To explicate the complex process of team collaboration and identify salient elements of team collaboration in paediatric rehabilitation.

Data Sources: After an initial search to define key features of team collaboration a systematic search on team collaboration and the key features was executed to identify salient elements. The systematic search was carried out in Index Medicus (MEDLINE), Educational Resource Information Clearinghouse (ERIC) and American Psychological Association (Psyc INFO) covering the period from January 1993 to December 2004.

Microarray analysis on Runx2-deficient mouse embryos reveals novel Runx2 functions and target genes during intramembranous and endochondral bone formation.

A major challenge in developmental biology is to correlate genome-wide gene expression modulations with developmental processes in vivo. In this study, we analyzed the role of Runx2 during intramembranous and endochondral bone development, by comparing gene expression profiles in 14.5 dpc wild-type and Runx2 (-/-) mice.

Microarray analysis reveals expression regulation of Wnt antagonists in differentiating osteoblasts.

Wnt signaling has been implicated in regulating bone formation by controlling osteoblast proliferation and function. Although stabilization of beta-catenin by Wnt has been shown to increase alkaline phosphatase expression and osteoblast differentiation, the precise role of Wnt signaling during the process of osteoblast differentiation is largely unknown. In this study, we used microarray technology to investigate expression regulation of Wnt signaling components during in vitro osteoblast differentiation.
