Abstract
Challenges in directed differentiation and survival limit the clinical use of stem cells despite their promising therapeutic potential in regenerative medicine. Nanotechnology has emerged as a powerful tool to address these challenges and enable precise control over stem cell fate. In particular, nanomaterials can mimic an extracellular matrix and provide specific cues to guide stem cell differentiation and proliferation in the field of nanotechnology. For instance, recent studies have demonstrated that nanostructured surfaces and scaffolds can enhance stem cell lineage commitment modulated by intracellular regulation and external stimulation, such as reactive oxygen species (ROS) scavenging, autophagy, or electrical stimulation. Furthermore, nanoframework-based and upconversion nanoparticles can be used to deliver bioactive molecules, growth factors, and genetic materials to facilitate stem cell differentiation and tissue regeneration. The increasing use of nanostructures in stem cell research has led to the development of new therapeutic approaches. Therefore, this review provides an overview of recent advances in nanomaterials for modulating stem cell differentiation, including metal-, carbon-, and peptide-based strategies. In addition, we highlight the potential of these nano-enabled technologies for clinical applications of stem cell therapy by focusing on improving the differentiation efficiency and therapeutics. We believe that this review will inspire researchers to intensify their efforts and deepen their understanding, thereby accelerating the development of stem cell differentiation modulation, therapeutic applications in the pharmaceutical industry, and stem cell therapeutics.

Autophagy 2024; 20:1897-1898. [PMID: 38477302 PMCID: PMC11262199 DOI: 10.1080/15548627.2024.2330042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2024] [Accepted: 03/09/2024] [Indexed: 03/14/2024] Open
Abstract
Embryonic stem cells (ESCs), with abilities of infinite proliferation (self-renewal) and to differentiate into distinct cell types (pluripotency), show attenuated inflammatory response against cytokines or pathogens, which is recognized as a unique characteristic of ESCs compared with somatic cells. However, the underlying molecular mechanisms remain unclear, and whether the attenuated inflammatory state is involved in ESC differentiation is completely unknown. Our recent study demonstrated that macroautophagy/autophagy-related protein ATG5 inhibits the inflammatory response of mouse ESCs (MmESCs) by promoting the degradation of BTRC/β-TrCP1 and further the downregulation of NFKB/NF-κB signaling. In addition, maintenance of an attenuated inflammation status in MmESCs is required for their differentiation. In conclusion, ATG5 is a key regulator for the regulation of inflammatory response and differentiation of MmESCs.

Protocol to test for the formation of ternary protein complexes in vivo or in vitro using a two-step immunoprecipitation approach. STAR Protoc 2024; 5:103080. [PMID: 38776227 PMCID: PMC11141244 DOI: 10.1016/j.xpro.2024.103080] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2024] [Revised: 04/02/2024] [Accepted: 04/30/2024] [Indexed: 05/24/2024] Open
Abstract
Co-immunoprecipitation (coIP) is an experimental technique to study protein-protein interactions (PPIs). However, single-step coIP can only be used to identify the interaction between two proteins and does not solve the interaction testing of ternary complexes. Here, we present a protocol to test for the formation of ternary protein complexes in vivo or in vitro using a two-step coIP approach. We describe steps for cell culture and transfection, elution of target proteins, and two-step coIP including western blot analyses. For complete details on the use and execution of this protocol, please refer to Li et al.1.
