AI Article Synopsis
Article Abstract
ASGR1 is a liver-specific surface marker that has been used to purify human pluripotent stem cell (PSC)-derived hepatocytes (iHeps). Furthermore, ASGR1 iHeps represents a more mature subpopulation of iHeps. To utilize this marker for optimizing iHep differentiation and purification, we substituted the stop coden of ASGR1 with a fluorescent reporter protein mCherry in a human iPSC line iPSN0052 via CRISPR/Cas9-mediated homologus recombination. The generated CIBi010-A enableds us to monitor ASGR1 expression during hepatic differentiation and thus can be used to optimize our hepatic differentiation procedures.

Late-onset hypogonadism (LOH) syndrome is characterized by age-related testosterone deficiency and negatively affects the quality of life of older men. A promising therapeutic approach for LOH syndrome is transplantation of testosterone-producing Leydig-like cells (LLCs) derived from human induced pluripotent stem cells (hiPSCs). However, previous studies have encountered obstacles, such as limited cell longevity, insufficient testosterone production, and inefficiency of differentiation.

Charcot-Marie-Tooth disease type 1A (CMT1A) is an inherited peripheral neuropathy caused by a duplication of the peripheral myelin protein 22 (PMP22) gene. It is primarily marked by Schwann cell dedifferentiation and demyelination, leading to motor and sensory deficits. Cyclic adenosine monophosphate (cAMP) is crucial for Schwann cell differentiation and maturation.

Background: Rodent models have been widely used to investigate skin development, but do not account for significant differences in composition compared to human skin. On the other hand, two-dimensional and three-dimensional engineered skin models still lack the complex features of human skin such as appendages and pigmentation. Recently, hair follicle containing skin organoids (SKOs) with a stratified epidermis, and dermis layer have been generated as floating spheres from human-induced pluripotent stem cells (hiPSCs).

Recent advances in drug design and compound synthesis have highlighted the increasing need for effective methods of toxicity evaluation. A specialized force sensor, known as the light wavelength-encoded "Chinese guzheng" is developed. This innovative sensor is equipped with optical fiber strings and utilizes a wavelength-encoded fiber Bragg grating (FBG) that is chemically etched to reduce its diameter.
