| Abstract | Wounds are one of the most frequently occurring medical complication. Stem cells were recently highlighted as a novel therapeutic approach to treating wounds, although some negative aspects of allogenic stem cell transplantation were observed, such as cellular source limitations and unknown side effects in vivo. To address and eliminate these side effects, we examined the wound healing effect of secretory factors released from human cord blood-derived stem cells (hCB-SCs) and human umbilical vascular endothelial cells (HUVECs) on cutaneous excisional wound models. The hCB-SCs retained endothelial progenitor cell characteristics and expressed MSC markers such as CD73, CD105, and CD44. Analysis of hCB-SC-conditioned medium (CM) indicated that hCB-SCs secrete distinctly unique cytokines and chemokines such as TGF-β, PDGF, bFGF, EGF, KGF, and VEGF, which are well known to be important in normal angiogenesis and wound healing. Furthermore, hCB-SCs also secreted stem cell-recruiting factors such as G-CSF and GM-CSF, whereas HUVECs did not. When CB-SC-CM was applied to wound sites, hCB-SC-CM accelerated the wound healing rate compared with HUVEC-CM- and control medium-treated groups. In addition, hCB-SC-CM treatment caused a more rapid re-formation of granulation tissue and re-epithelialization of wounds, which indicates that the therapeutic effect of hCB-SC-CM is due to secreted stem cell-recruiting factors from stem cells, not just from endothelial lineage cells. Taken together, these results suggest that secretory factors released from stem cells, not just from endothelial cells, could be an important mediator of stem cell therapy in ischemic tissue diseases. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
