Women in (Dis)placement: The Field of Studies on Migrations, Social Remittances, Care and Gender in Chile

This article presents current perspectives on the gender approach to the study of migration in Chile between 1990 and 2018, contextualizing it in light of international debates in the social sciences. We will discuss how the feminization and the growth of Latin American migrations have given rise to a prolific field of research, as exemplified by studies conducted in central and northern Chile. We will show how the concepts of social remittances and caregiving permeate the Chilean debate on migrant women. We conclude with reflections on topics and perspectives to be incorporated into the Chilean research agenda on gender and migration.Se presenta un estado del arte sobre el enfoque de género en los estudios de la migración en Chile entre 1990 y 2018, contextualizándolo a la luz de debates internacionales de las ciencias sociales. Abordaremos cómo la feminización y el incremento de las migraciones latinoamericanas inauguran un prolijo campo de investigaciones, articulado a través de estudios desarrollados en el centro y en el norte de Chile. Señalaremos cómo los conceptos de remesas sociales y cuidados permean el debate chileno sobre las mujeres migrantes. Finalizamos con reflexiones sobre temas y perspectivas a ser incorporados en la agenda chilena de investigaciones sobre género y migración.The authors would like to thank the Chilean National Commission for Scientific and Technological Research (CONICYT) for funding the study that led to this article through Fondecyt Regular Project number 1160683: “Ser Mujer Mayor en Santiago.

Screening ethnically diverse human embryonic stem cells identifies a chromosome 20 minimal amplicon conferring growth advantage

The International Stem Cell Initiative analyzed 125 human embryonic stem (ES) cell lines and 11 induced pluripotent stem (iPS) cell lines, from 38 laboratories worldwide, for genetic changes occurring during culture. Most lines were analyzed at an early and late passage. Single-nucleotide polymorphism (SNP) analysis revealed that they included representatives of most major ethnic groups. Most lines remained karyotypically normal, but there was a progressive tendency to acquire changes on prolonged culture, commonly affecting chromosomes 1, 12, 17 and 20. DNA methylation patterns changed haphazardly with no link to time in culture. Structural variants, determined from the SNP arrays, also appeared sporadically. No common variants related to culture were observed on chromosomes 1, 12 and 17, but a minimal amplicon in chromosome 20q11.21, including three genes expressed in human ES cells, ID1, BCL2L1 and HM13, occurred in >20% of the lines. Of these genes, BCL2L1 is a strong candidate for driving culture adaptation of ES cells
