Liver Development, Regeneration, and Carcinogenesis [PDF]

open access: yes, 2010
The identification of putative liver stem cells has brought closer the previously separate fields of liver development, regeneration, and carcinogenesis. Significant overlaps in the regulation of these processes are now being described.

Purines as potential morphogens during embryonic development [PDF]

open access: yes, 2012
Components of purinergic signalling are expressed in the early embryo raising the possibility that ATP, ADP and adenosine may contribute to the mechanisms of embryonic development.

Meta-analysis of the incidence of pregnancy losses in dairy cows at different stages to 90 days of gestation

open access: yesJDS Communications, 2023
Pregnancy losses are a biological challenge and economically important in dairy herds. A meta-analysis was conducted to quantify losses in 4 periods from 19 to 90 d of pregnancy corresponding to the physiological development of gestation in dairy cows. A

Slow Turning Lateral Vessel Bioreactor Improves Embryoid Body Formation and Cardiogenic Differentiation of Mouse Embryonic Stem Cells. [PDF]

open access: yes, 2013
Embryonic stem cells (ESCs) have the ability to form aggregates, which are called embryoid bodies (EBs). EBs mimic early embryonic development and are commonly produced for cardiomyogenesis.

Revisiting the enigmatic cortical calretinin-expressing interneurons

open access: yesFrontiers in Neuroanatomy, 2014
Cortical calretinin (CR)-expressing interneurons represent a heterogeneous subpopulation of about 10-30% of GABAergic interneurons, which altogether total ca. 12-20% of all cortical neurons.

Prenatal Development and Function of Human Mononuclear Phagocytes

open access: yesFrontiers in Cell and Developmental Biology, 2021
The human mononuclear phagocyte (MP) system, which includes dendritic cells, monocytes, and macrophages, is a critical regulator of innate and adaptive immune responses. During embryonic development, MPs derive sequentially in yolk sac progenitors, fetal

Differential Hox expression in murine embryonic stem cell models of normal and malignant hematopoiesis [PDF]

open access: yes, 2011
The Hox family are master transcriptional regulators of developmental processes, including hematopoiesis. The Hox regulators, caudal homeobox factors (Cdx1-4), and Meis1, along with several individual Hox proteins, are implicated in stem cell expansion ...

Establishment of pluripotent cell lines from vertebrate species - Present status and future prospects [PDF]

open access: yes, 1999
Pluripotent embryonic stem (ES) cells are undifferentiated cell lines derived from early embryos and are capable of unlimited undifferentiated proliferation in vitro.

Modeling Human Organ Development and Diseases With Fetal Tissue–Derived Organoids

open access: yesCell Transplantation, 2022
Recent advances in human organoid technology have greatly facilitated the study of organ development and pathology. In most cases, these organoids are derived from either pluripotent stem cells or adult stem cells for the modeling of developmental events
