Topic title: Biomaterials for stem cell fate regulation and neuro-organoid construction


In the realm of tissue regeneration, stem cell-based treatments hold vast clinical promise. The maintenance of stem cell pluripotency and the efficient induction of lineage-specific differentiation are pivotal for ensuring their therapeutic efficacy. Harnessing the potential of bioactive materials to manipulate stem cell fate and construct organoid has emerged as a focal point of research and a critical avenue for innovative breakthroughs.

Our research has recently devised a high-throughput AI framework termed DeepScreen. We successfully trained a classification model that can accurately forecast the fate of neural stem cell differentiation by convolutional neural networks. The resultant DeepScreen platform represents an all-encompassing, intelligent high-throughput screening system that readily accommodates diverse neurotrophic factors, biomaterials, and biomaterial-factor combinatorial arrangements. By streamlining and expediting the screening and identification of novel therapeutics pertaining to neural protection and regeneration, it possesses the potential to achieve significant advancements in the field of biomaterial-guided stem cell fate modulation and central nervous system regeneration research.

Based on this AI screening system, we designed and validated investigated the influence of layered double hydroxide (LDH) materials, constructed with varying compositions of different metal elements, on the self-renewal and differentiation capabilities of various stem cells, along with the underlying molecular mechanisms. Previous research has shown that the addition of Mg/Al-LDH during the proliferation culture of mouse embryonic stem cells (mESCs) enhances their self-renewal capacity. Additionally, the different particle sizes of LDH have varying effects on mESC self-renewal. Treating mESCs with LDH composed of different cations, transcriptomic and proteomic screening revealed that compared to Mg/Al-LDH, Mg/Fe-LDH more effectively activates the LIF/PI3K/AKT signaling pathway. Subsequently, it activates downstream TET1/2 and promotes DNA demethylation processes in mESCs. Recent studies have demonstrated that LDH optimized with specific elemental ions enhances chondrogenic differentiation of human mesenchymal stem cells (hMSCs) and activates the Focal adhesion signaling pathway. Based on the above researches, we focus on the construction of engineered spinal cord organoids (enTsOrg) using LDH. enTsOrg exhibits the precise structure and cellular composition of the thoracic spinal cord segment and participates in axon regeneration and functional recovery in a complete SCI animal model.

In summary, our research focuses on investigating the functionality and mechanisms of LDH in stem cell fate regulation and tissue engineering through the design, optimization, and synthesis of LDH nanomaterials. In-depth studies of LDH, considering its significant variations in regulating stem cell functions and mechanisms under different culture environments, will provide new strategies for developing composite therapeutic systems for tissue regeneration and biomedical applications.
