摘要：: The present invention refers to an optimized and defined method for isolation and preservation of precursor cells from human umbilical cord. Besides being reproducible and 100% reliable, in terms of the number of samples processed, the method results in a high and defined number of precursor cells, being the majority obtained after a single adhesion and expansion/multiplication phase ex vivo (thus granting cell phenotype), in a shorter time frame than what was previously described in the state-of-the-art. With this method, it is possible to obtain, in 9 days, after direct freezing of a cell fraction, and after one expansion/multiplication phase ex vivo (end of P0) of the majority of the cells, about 8.6(±0.1)×105 cells/gram of processed umbilical cord. In turn, the characteristics of the cells allow, for example, after 35 days, obtaining an average of 7.7×1015 cells, with precursor phenotype, from 100% of processed umbilical cord samples. The method, because it is simple, robust and 100% reliable, can be performed under good manufacturing practices (GMP) in laboratories dedicated to cell therapy in humans. Furthermore, the method has applications in the pharmaceutical, cosmetic and biotechnology areas.
