Cytogenetics evaluation of 261 couples with first-trimester recurrent pregnancy loss: A prevalent case–control study

Journal of Marine Medical Society, 2023
Introduction: Recurrent pregnancy loss (RPL) is a common occurrence which affects approximately 15-20% of couples. Chromosomal abnormality is an important cause of recurrent abortions especially if either of the partner is a carrier of balanced ...

Establishment and optimization of the two‐step induction system for generating primordial germ cell‐like cells from chicken embryonic stem cells

FEBS Open Bio, EarlyView.
This study optimizes a two‐step induction system to generate PGCLCs from chicken ESCs. The induced cells express germline markers and migrate to gonads in ovo, offering a novel approach for avian genetic resource conservation. Primordial germ cells (PGCs) are the progenitor cells of sperm and eggs.
