LGR4, Not LGR5, Enhances hPSC Hematopoiesis by Facilitating Mesoderm Induction via TGF-Beta Signaling Activation

open access: yesCell Reports, 2020
Summary: Attempts to generate functional blood cells from human pluripotent stem cells (hPSCs) remain largely unsuccessful, mainly due to the lack of understanding of the regulatory network of human hematopoiesis.

Normal levels of p27Xic1 are necessary for somite segmentation and determining pronephric organ size [PDF]

open access: yes, 2009
The Xenopus laevis cyclin dependent kinase inhibitor p27Xic1 has been shown to be involved in exit from the cell cycle and differentiation of cells into a quiescent state in the nervous system, muscle tissue, heart and retina.

Functionally distinct roles for T and Tbx6 during mouse development

open access: yesBiology Open, 2020
The mouse T-box transcription factors T and Tbx6 are co-expressed in the primitive streak and have unique domains of expression; T is expressed in the notochord, while Tbx6 is expressed in the presomitic mesoderm.

Fate mapping identifies the origin of SHF/AHF progenitors in the chick primitive streak [PDF]

open access: yes, 2012
Heart development depends on the spatio-temporally regulated contribution of progenitor cells from the primary, secondary and anterior heart fields. Primary heart field (PHF) cells are first recruited to form a linear heart tube; later, they contribute ...

The emergence of Pax7-expressing muscle stem cells during vertebrate head muscle development [PDF]

open access: yes, 2015
Pax7 expressing muscle stem cells accompany all skeletal muscles in the body and in healthy individuals, efficiently repair muscle after injury. Currently, the in vitro manipulation and culture of these cells is still in its infancy, yet muscle stem ...

Evidence for a Role of the Lateral Ectoderm in Drosophila Mesoderm Invagination

open access: yesFrontiers in Cell and Developmental Biology, 2022
The folding of two-dimensional epithelial sheets into specific three-dimensional structures is a fundamental tissue construction mechanism in animal development.

A system to enrich for primitive streak-derivatives, definitive endoderm and mesoderm, from pluripotent cells in culture [PDF]

open access: yes, 2012
Two lineages of endoderm develop during mammalian embryogenesis, the primitive endoderm in the pre-implantation blastocyst and the definitive endoderm at gastrulation.

Fibroepithelial Polyp Originating from the Nasal Septum

open access: yesTurkish Archives of Otorhinolaryngology, 2019
Fibroepithelial polyp (FEP) is a rare clinical condition of mesodermal origin, covered usually by squamous epithelium, originating most frequently from the skin, genitourinary and lower respiratory tract.

Early patterning and specification of cardiac progenitors in gastrulating mesoderm

open access: yeseLife, 2014
Mammalian heart development requires precise allocation of cardiac progenitors. The existence of a multipotent progenitor for all anatomic and cellular components of the heart has been predicted but its identity and contribution to the two cardiac ...
