Brazilian co-authorships in regenerative medicine publications: inequalities in emerging countries scientific collaboration

International scientific cooperation has become a key factor for emerging countries to improve research advancement, publication and funding. An analysis of local publications indexed in the Web of Science and co-authored between Brazilian researchers and non-residents was carried out, in the context of an analytical discussion on global scientific cooperation and with the aim of illustrating changes in the last two decades in regenerative medicine regarding this topic. The article concluded that in the last decade Brazil increased scientific co-authorships significantly domestically and with advanced country authors, especially with American authors, but also to a lesser degree with those of other emerging economies in and beyond Latin American. Local researchers have also published on their own several articles of global impact, revealing the academic quality attained in local sciences related to the area. Collaboration has undoubtedly opened doors for Brazilian regenerative medicine globally, but historical scientific inequalities remain
