Livestock pluripotent stem cells, derived either from early embryos or induced through somatic cell reprogramming technology, possess the unique ability to self-renew, maintain an undifferentiated state and differentiate into various cell types. Consequently, the generation of PSCs from agricultural animal species holds great potential for applications in livestock breed improvement, rapid propagation, disease modelling and xenotransplantation. However, compared to the great achievements made in mouse and human pluripotent stem cells research, the generation of livestock pluripotent stem cells still remains challenging. This article offers an overview of the classification, regulatory mechanisms of pluripotency, and developmental history of livestock pluripotent stem cells, while also anticipating their future application prospects. These insights provide valuable references for the reproduction and breeding of large livestock.

Extracellular vesicles (EVs) are secreted nanoparticles composed of a lipid bilayer that carry lipid, protein, and nucleic acid cargo between cells as a mode of intercellular communication. Although EVs can promote tissue repair in mammals, their roles in animals with greater regenerative capacity are not well understood. Planarian flatworms are capable of whole-body regeneration due to pluripotent somatic stem cells called neoblasts that proliferate in response to injury.

Dystrophic neurites (also termed axonal spheroids) are found around amyloid deposits in Alzheimer's disease (AD), where they impair axonal electrical conduction, disrupt neural circuits and correlate with AD severity. Despite their importance, the mechanisms underlying spheroid formation remain incompletely understood. To address this, we developed a proximity labeling approach to uncover the proteome of spheroids in human postmortem and mouse brains.

Activation of endogenous full-length utrophin, a dystrophin homolog, presents an attractive therapeutic strategy for Duchenne muscular dystrophy (DMD), regardless of mutation types and loci. However, current dCas9-based activators are too large for efficient adeno-associated virus delivery, and the feasibility and durability of such treatments remain unclear. Here, we develop a muscle-targeted utrophin activation system using the compact dCasMINI-VPR system, termed MyoAAV-UA.

The acute and large area skin healing has been an intractable problem for both clinician and patient. Exosomes derived from human-induced pluripotent stem cells (hiPSC-Exos) have been a novel promising cell-free treatment on skin damage repair. In this study, in vivo skin trauma model of full-layer skin damage on mouse back and in vitro skin-like trauma model of human keratinocytes (HaCaT) scratches were established to investigate the effects of hiPSC-Exos on the acute wound healing, and its potential regulation mechanism would be tried to explore.

The increasing ethical concerns and regulatory restrictions surrounding animal testing have accelerated the development of advanced models that more accurately replicate human physiology. Among these, stem cell-based systems and organoids have emerged as revolutionary tools, providing ethical, scalable, and physiologically relevant alternatives. This review explores the key trends and driving factors behind the adoption of these models, such as technological advancements, the principles of the 3Rs (Replacement, Reduction, and Refinement), and growing regulatory support from agencies like the OECD and FDA.
