A lot of links needed to be corrected. The reason is given on eCM journal website: “The eCM Journal (Eur Cell Mater) council decided in June 2017 to discontinue and remove all old supplements published in eCM journal. This decision was based upon the unfortunate situation that randomly since 2013 eCM conference abstract supplements were being used in the JCR / Clarivate Analytics calculation of eCM journal’s impact factor. […] These Meeting Abstracts are being hosted on a separate new web site eCM conferences, which is not part of the eCM journal.”
The SSB/SSB+RM conference abstracts can now be found the SSB+RM abstract website on eCM conferences.
