Navigating the Complexity: A Comprehensive Review of GSK‐3 Inhibition in Regenerative Medicine

Medicinal Research Reviews, EarlyView.
ABSTRACT Glycogen synthase kinase‐3 (GSK‐3) is a central regulator of numerous cellular signaling pathways, with critical roles in metabolism, proliferation, differentiation, and tissue regeneration. This review explores the multifaceted effects of pharmacological GSK‐3 inhibition across multiple body districts, focusing on its highly context‐dependent

A new old species of Tetracera (Dilleniaceae) from Espinhaço Range, Brazil

Nordic Journal of Botany, EarlyView.
Tetracera is the only genus within Dilleniaceae with a pantropical distribution. During efforts for a taxonomic revision of the neotropical species, we identified incongruences between application of names and their taxonomic identities, based on protologue and type specimen analysis. Here we describe a new species for the genus bearing a single carpel

The effects of overexpression of lamin a and two mutants associated with premature aging on stem cell differentiation and proliferation. [PDF]

, 2007
The nuclear lamina is composed of A and B-type lamins and performs a number of functions within the nucleus. Mutations within lamins give rise to a group of diseases called laminopathies including autosomal dominant Emery-Dreifuss muscular dystrophy and ...

Advances in deep‐tissue fluorescence imaging through optical clearing: A review

VIEW, EarlyView.
Optical clearing refers to techniques that are used to improve the optical transparency of biological tissues. Optical clearing enables imaging of deeper lying tissues as well as 3D volumetric imaging of whole organs. This review examines reports on the integration of optical clearing with advanced fluorescence imaging techniques, with particular ...

Children Born Using Ejaculated Sperm From Men With Klinefelter Syndrome. Is Sperm Production Associated With Testicular Volume?

Andrology, EarlyView.
ABSTRACT Background A large number of children have been born using testicular sperm from men with Klinefelter syndrome (KS), whereas reports of children conceived using ejaculated sperm are rare. Objective To review all published cases of children conceived using ejaculated sperm from men with KS, assess their health and karyotype, and evaluate ...

Hair follicle regeneration technology: from microenvironment regulation to functional reconstruction

Frontiers in Bioengineering and Biotechnology
Hair loss is a common clinical condition that substantially impairs patients’ physical and mental health and quality of life. Hair loss is closely associated with disruption of hair follicle microenvironment homeostasis.

Hair Follicle Dermal Cells Support Expansion of Murine and Human Embryonic and Induced Pluripotent Stem Cells and Promote Haematopoiesis in Mouse Cultures

Stem Cells International, 2018
In the hair follicle, the dermal papilla (DP) and dermal sheath (DS) support and maintain proliferation and differentiation of the epithelial stem cells that produce the hair fibre.

The Impact of Common Medications on Male Fertility: An Updated Systematic Review

Andrology, EarlyView.
ABSTRACT Background Compared with those of cytotoxic treatments, the potential effects of common medications on the fertility of men trying to conceive currently or planning to conceive in the future are less well described. The use of common medications may modify the gonadotropic axis, spermatogenesis, and epididymal maturation or alter male ...
