20130224277 | POROUS POLYSACCHARIDE SCAFFOLD COMPRISING NANO-HYDROXYAPATITE AND USE FOR BONE FORMATION - The present invention relate to three dimensional porous polysaccharide matrices able to induce mineralisation of a tissue in osseous site, as well as in non-osseous site, in the absence of stem cells or growth factors. | 08-29-2013 |
20140349330 | METHODS FOR AGGREGATION AND DIFFERENTIATION OF MAGNETIZED STEM CELLS - The invention relates to a process which enables optimal aggregation of cells, typically of stem cells, promoting the organisation thereof and advantageously the differentiation thereof, in particular in the context of the formation of a tissue substitute. This process comprises exposing pretreated cells to a magnetic field and makes it possible to obtain large cell aggregates, even prepared in the absence of support matrix and/or of growth factor. The invention also relates to the cell aggregates that can be obtained using such a process and also to the uses thereof as tissue initiators with a view to obtaining a tissue structure of interest in vitro, ex vivo or in vivo. Moreover, it relates to the resulting tissue structures and to the uses thereof in research or in therapy as tissue substitutes. The present application also provides a method which advantageously makes it possible to monitor the development of the tissue of interest in vivo. | 11-27-2014 |
