Biohellenika exhausting all the possibilities that are provided with the birth of the child for the collection of the greatest number of stem cells, apart from the classical method for collection with the puncture of the umbilical cord, proceeds also to the drainage of the placenta. This way of collection allows the collection of the cells that have remained in the interior of the placenta after the classical collection process. For this reason the whole placenta is transferred under special sterile conditions to the lab. A great number of stem cells are trapped in the placenta vessels. With the special method published from the scientific team of Biohellenika all these cells are collected and added to the first classical stem cell collection. Finally an also double number of stem cells are collected, that would be disposed with the placenta if the second collection was not performed.  This special method of collection of stem cells from the interior of the placenta was awarded a prize in the 15^th Panhellenic Conference of Transplantation in Thessaloniki in December 2007 and was referred for one week on February 2008 in the internet as the most interesting medical publication in the international medical press and was published in the Transplantation Proceedings 2007, 39 (10): 3380-4.
