This work aims to analyze the co-authorship network of Brazilian scientific production around stem cells, from 2001 to 2020. This is a longitudinal, quantitative and descriptive research, based on the analysis of social networks, with the co-occurrence of authors as the unit of measurement and, the unit of analysis, the citing author. The results present the metrics of scientific production and networks referring to the largest component of each co-authorship network, from the four sub-periods analyzed: 2001-2005, 2006-2010, 2011-2015 and 2016-2020. Finally, it is inferred that the growing production of studies in stem cells, in Brazil, and the increase in the co-authorship network in the analyzed periods were leveraged due to the increase in the number of authors and the actions promoted by the Ministry of Health, in partnership with the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq). As future analysis perspectives, this work intends to identify the most relevant authors, the predominant areas and subjects of study and the temporal evolution of stem cell research in Brazil.
