Comparative in situ characterization of erythroid cells found throughout the developing tongue tissue, circulation, and liver of fetal mice.

Background: Erythroid cells contribute to embryonic organ development and adult tissue repair supplying oxygen to tissues. During mouse development, the primitive erythroid cells produced in the extraembryonic blood islands of the yolk sac begin to circulate as immature and nucleated erythroblasts with the onset of cardiac contractions around embryonic day 9.5 (E9.

The functions and factors governing fungal communities and diversity in agricultural waters: insights into the ecosystem services aquatic mycobiota provide.

Introduction: Fungi are essential to the aquatic food web, nutrient cycling, energy flow, and ecosystem regulation. Fungal community structures in water can be influenced by adjacent terrestrial environments, which drive and control some ecosystem services they provide. However, the roles of freshwater fungal communities remain underexplored compared to bacterial communities in this context.

Facility wastewater monitoring as an effective tool for pandemic infection control: An experience in COVID-19 pandemic with long-term monitoring.

Introduction: Since the first report of a novel coronavirus infection caused by SARS-CoV-2 in late 2019, the infection has spread rapidly and had a significant impact on our lives. In the early stages of the COVID-19 pandemic, there was no adequate testing system in place, despite an urgent need for infection control measures in student dormitories.

Methods: We have been monitoring SARS-CoV-2 in wastewater as part of our infection control efforts in the university facilities since fall 2020.

Generation of bone-specific lysyl hydroxylase 2 knockout mice and their phenotypes.

Lysyl hydroxylase 2 (LH2) catalyzes the hydroxylation of lysine residues in the telopeptides of type I collagen. This modification is critical for the formation of stable hydroxylysine-aldehyde derived collagen cross-links, thus, for the stability of collagen fibrils. Though dysfunction of LH2 causes Bruck syndrome, recessive osteogenesis imperfecta with joint contracture, the molecular mechanisms by which LH2 affects bone formation are still not well understood.

Spatiotemporal expression profiles of c-Mpl mRNA in the tooth germ: Comparative expression dynamics of vascularization-related genes.

Background: Vascularization is an essential event for both embryonic organ development and tissue repair in adults. During mouse tooth development, endothelial cells migrate into dental papilla during the cap stage, and form blood vessels through angiogenesis. Megakaryocytes and/or platelets, as other hematopoietic cells, express angiogenic molecules and can promote angiogenesis in adult tissues.
