Dr Mirjam van der Wel, from Animal Anti-Cruelty League (AACL) South Africa, came to visit TCG last week. Mirjam is a collaborator of our ongoing CTVT projects and had sent us hundreds of CTVT samples in the past few years. She spent a week with TCG members and investigated the journey of CTVT tissue samples from the biopsy to genomic DNA sequencing.
