Scientists Report Creating the First Embryo With Human and Non-Human Primate Cells
In a ground-breaking experiment, researchers have successfully created the first human-monkey chimera. The work, published in the journal Cell, describes the the first embryo containing both human and monkey cells that was cultured for 20 days. Led by Juan Carlos Izpisua Belmonte, the study represents the culmination of decades of work in understanding early embryo development in non-human species, which Belmonte hopes will now apply to humans. But it is bound to raise serious ethical questions about the implications of combining human cells with those from a different species (even if it is a closely related one), and the report was accompanied by commentary from ethicists on how the work should be interpreted and what the careful next steps should be in pursuing this line of study. Belmonte, a professor in the gene expression laboratory at the Salk Institute for Biological Studies and well-respected for his work in embryo development, is very clear about why he pursued the experiment, and where he hopes it will lead. Creating cross-species mutants to capitalize on specific physical features or characteristics, X-Men style, was most definitely not the goal. In interviews with TIME on the experiment as it progressed since 2019, he carefully laid out the biological mysteries he hoped to solve, and the gaps in knowledge about early development he wanted to fill. The earliest steps that human embryos take, he says, are the “biggest mystery of human development. While we k...

Authors: Musio F Abstract INTRODUCTION: Anemia has and will continue to be a central theme in medicine particularly as clinicians are treating a burgeoning population of complex multi-organ system processes. As a result of multiple randomized controlled trials (RCTs), meta-analyses, and societal recommendations overly restrictive paradigms and under-administration of erythropoiesis stimulating agents (ESAs) have likely been followed by clinicians among all specialties. AREAS COVERED: A review of anemia in the context of chronic kidney disease, hematologic malignancies and cancer is presented with focus on the e...

Conclusions: This review results revealed a low utilization of postnatal care service. Antenatal care service utilization has a positive effect on postnatal care service utilization. Policymakers and programmers better considered more antenatal care service use as one strategy of enhancing the utilization of postnatal care service. PMID: 33029402 [PubMed - in process]
