Hematopoietic stem cells are a unique population of tissue-resident multipotent cells with an extensive ability to self-renew and regenerate the entire lineage of differentiated blood cells. Stem cells reside in a highly specialized microenvironment with surrounding supporting cells, forming a complex and dynamic network to preserve and maintain their function. The survival, activation, and quiescence of stem cells are largely influenced by niche-derived signals, with aging niche contributing to a decline in stem cell function.

The rising threat of antimicrobial resistance among pathogens highlights the critical need for novel antimicrobial agents. This study explores the potential of natural products by investigating hexane extracts from the marine sponge Haliclona fibulata (HF) for their antibacterial efficacy. The well diffusion method of HF extract showed significant antibacterial activity against P.

Severe damage to the intrahepatic biliary duct (IHBD) network occurs in multiple human advanced cholangiopathies, such as primary sclerosing cholangitis, biliary atresia and end-stage primary biliary cholangitis. Whether and how a severely damaged IHBD network could reconstruct has remained unclear. Here we show that, although the gallbladder is not directly connected to the IHBD, there is a common hepatic duct (CHD) in between, and severe damage to the IHBD network induces migration of gallbladder smooth muscle cells (SMCs) to coat the CHD in mouse and zebrafish models.

A key property of the circadian clock is that it is reset by light to remain synchronized with the day-night cycle. An attractive model to explore light input to the circadian clock in vertebrates is the zebrafish. Circadian clocks in zebrafish peripheral tissues and even zebrafish-derived cell lines are entrainable by direct light exposure thus providing unique insight into the function and evolution of light regulatory pathways.

While cisplatin is an effective anti-tumor treatment, it induces ototoxicity through mechanisms involving DNA damage, oxidative stress, and programmed cell death. Rho-associated coiled-coil-containing protein kinase (ROCK) is essential for numerous cellular processes, including apoptosis regulation. Studies have suggested that ROCK inhibitors could prevent apoptosis and promote regeneration.
