Innovations in Training: Toward Mitigating "Eternal post-docdum" in Stem Cell Research.

The Networks of Centres of Excellence (NCE) is an innovative model of large-scale research networks that began in Canada in 1989, and has since been adopted by numerous countries around the globe. The Canadian Stem Cell Network (SCN), an NCE that has fostered stem cell research and innovation in Canada, has supported over 1800 trainees since its inception in 2001. In the present study we assess the impact of such a network on its research trainees professional decision-making and movements. A database populated by the SCN between the years 2001-2013 was utilized to describe trainee professional movement between sectors and geographic regions. Focus groups of SCN trainees (n = 27) were carried out and major themes and subthemes were derived from the discourse using a thematic analysis approach. We found that most SCN trainees remained in Canada and in academic positions after leaving the SCN. Trainees expressed a desire to work in environments where their scientific interests and ideas are nurtured, where funding is stable, and where supervisor mentorship is readily accessible. SCN trainees value the unique opportunities provided by the NCE, including opportunities to network with peers, to attend various workshops and to broaden their knowledge and interest base beyond science and academia. Challenges faced by postdoctoral fellows and recommendations for future NCEs are also discussed. The findings here can be used to form evidence-based recommendations for future research networks and for policy pertaining to the recruitment and retention of highly qualified personnel in stem cell research.
