Lipofection improves gene targeting efficiency in E14 TG2a mouse embryonic stem cells [PDF]

open access: yes, 2009
Electroporation has been the method of election for transfection of murine embryonic stem cells for over 15 years; however, it is a time consuming protocol because it requires large amounts of DNA and cells, as well as expensive and delicate equipment ...

Hypoxia Signaling Pathway in Stem Cell Regulation: Good and Evil [PDF]

open access: yes, 2018
Purpose of Review: This review summarizes the role of hypoxia and hypoxia-inducible factors (HIFs) in the regulation of stem cell biology, specifically focusing on maintenance, differentiation, and stress responses in the context of several stem cell ...

Region‐to‐Region Unidirectional Connection In Vitro Brain Model for Studying Directional Propagation of Neuropathologies

open access: yesAdvanced Functional Materials, EarlyView.
A unidirectional cerebral organoid–organoid neural circuit is established using a microfluidic platform, enabling controlled directional propagation of electrical signals, neuroinflammatory cues, and neurodegenerative disease–related proteins between spatially separated organoids.

CXCL13 suppresses liver regeneration through the negative regulation of HGF signaling

open access: yesCell Death and Disease
Insufficient liver regeneration increases the risk of postoperative liver failure following liver transplantation or partial hepatectomy (PHx). Numerous growth factors and cytokines are related to liver regeneration; however, the underlying mechanisms ...

Distinct molecular profile and restricted stem cell potential defines the prospective human cranial neural crest from embryonic stem cell state

open access: yesStem Cell Research, 2020
Neural crest cells are an embryonic multipotent stem cell population. Recent studies in model organisms have suggested that neural crest cells are specified earlier than previously thought, at blastula stages.

Stem cell populations in the heart and the role of Isl1 positive cells [PDF]

open access: yes, 2013
Cardiac progenitor cells are multipotent stem cells isolated from both embryonic and adult hearts in several species and are able to differentiate at least into smooth muscle cells, endothelial cells and cardiomyocytes.

High‐Spatiotemporal‐Resolution Transparent Thermoelectric Temperature Sensor Arrays Reveal Temperature‐Dependent Windows for Reversible Photothermal Neuromodulation

open access: yesAdvanced Functional Materials, EarlyView.
Thermoelectric temperature sensors are developed that directly measure heat changes during optical‐based neural stimulation with millisecond precision. The sensors reveal the temperature windows for safe reversible neural modulation: 1.4–4.5 °C enables reversible neural inhibition, while temperatures above 6.1 °C cause permanent thermal damage.

Conventional pluripotency markers are unspecific for bovine embryonic-derived cell-lines [PDF]

open access: yes, 2013
Bovine embryonic stem cells are of potentially big value in transgenic research and studies of lineage commitment and development. Nevertheless, key aspects of the establishment of bovine embryonic stem cells such as the identification of specific ...

Identification of side population cells in mouse primordial germ cells and prenatal testis [PDF]

open access: yes, 2011
In mammals, the stem cells of spermatogenesis are derived from an embryonic cell population called primordial germ cells (PGCs). Spermatogonial stem cells displaying the "side population" (SP) phenotype have been identified in the immature and adult ...

Ultrahigh‐Yield, Multifunctional, and High‐Performance Organic Memory for Seamless In‐Sensor Computing Operation

open access: yesAdvanced Functional Materials, EarlyView.
Molecular engineering of a nonconjugated radical polymer enables a significant enhancement of the glass transition temperature. The amorphous nature and tunability of the polymer, arising from its nonconjugated backbone, facilitates the fabrication of organic memristive devices with an exceptionally high yield (>95%), as well as substantial ...
