Twelve people in three states developed infections and were hospitalized after they got infusions or injections of stem cell products derived from umbilical cord blood that were contaminated with bacteria. See the CNN Article for more details.
The FDA also recently issued a warning letter to Genetech Inc one of the major suppliers of cord stem cells, for many failures in their processes, including the failure to register the umbilical cord product as a cell drug as well the failure to undergo a full clinical screening of the unapproved product. See here for the full FDA warning letter.
We do not use any umbilical cord products or unapproved FDA products.
