Background Mesenchymal stem cells-derived exosomes, crucial in regenerative medicine, have been explored for their potential the functional modification of bone scaffolds. Objective To design a functionally modified biomimetic nanohydroxyapatite using exosomes and explore its effects on regeneration. Methods A (named as tHA) was fabricated previous methods polydopamine (pDA) structure template, (Exo) derived from periodontal ligament cells (PDLSCs) were used to modify tHA scaffold material through pDA. The composite (tHA-Exo) proliferation osteogenic differentiation investigated. Furthermore, effect regeneration also evaluated vivo. Results Exosomes can be loaded onto via pDA tHA-Exo releases sustained stable manner. showed improved cytocompatibility compared controls. Additionally, significantly enhanced PDLSCs. More importantly, animal experiments shown that could dramatically promote Conclusion nanoparticles, by PDLSCs-Exo pDA, promoted improving potential, which serve promising promoting

ABSTRACT Gliomas are the most ordinary primary virulent brain tumours and commonly used clinical treatments include tumour resection, radiation therapy chemotherapy. Although significant progress has been made in recent years progression‐free survival (PFS) overall (OS) for patients with high‐grade gliomas, prognosis remains poor. Chemoresistance refers to phenomenon of decreased sensitivity cells drugs, resulting reduced or ineffective drug efficacy, is an important cause failure Exosomes, a type extracellular vesicle, secreted by cancer various stromal microenvironment (TME) transfer their inclusions cells, increasing chemoresistance. Furthermore, depletion exosomes reverses certain detrimental effects on metabolism restores chemotherapeutic agents. Here, we summarised correlation between resistance agents glioma patients, mechanisms action involved value. We aimed afford new thoughts research, diagnosis intervention chemoresistance patients.

Mineralization is a key biological process that required for the development and repair of tissues such as teeth, bone cartilage. Exosomes (Exo) are subset extracellular vesicles (~50–150 nm) secreted by cells contain genetic material, proteins, lipids, nucleic acids, other substances have been extensively researched oral tissue regeneration. However, Exo-free biomaterials or exosome treatments exhibit poor bioavailability lack controlled release mechanisms at target site during By encapsulating Exos into like hydrogels, these disadvantages can be mitigated. Several engineering approaches, those wound healing processes in diabetes mellitus, treatment osteoarthritis (OA) cartilage degeneration, intervertebral disc cardiovascular diseases, etc., exploited to deliver exosomes containing variety therapeutic diagnostic cargos tissues. Despite significant efficacy Exo-laden their use mineralized tissues, tissue, very sparse. This review aims explore summarize literature related potential hydrogel-encapsulated provides insight practical procedures future clinical techniques.
