Development of Amniotic Epithelial Stem Cells Secretome-Loaded Inverse Electron Demand Diels-Alder-Cross-Linked Hydrogel as a Potential Immunomodulatory Therapeutical Tool.

Article Synopsis
- Amniotic epithelial stem cells (AEC) have regenerative potential, particularly through their conditioned medium (AEC-CM), which shows immunomodulatory and regenerative effects.
- A novel hydrogel made from hyaluronic acid and polyethylene glycol was developed to encapsulate AEC-CM, with features like fast cross-linking and sustained growth factor release over 14 days.
- Studies demonstrate that the encapsulated AEC-CM significantly enhances the suppression of peripheral blood mononuclear cells and promotes a shift towards the beneficial M2 macrophage phenotype, suggesting its viability as an immunomodulatory treatment for tissue regeneration.

Background: Immune checkpoint inhibitors (ICIs) are a cornerstone therapy for advanced renal cell carcinoma (RCC). However, significant rates of primary resistance hinder their efficacy, and the underlying mechanisms remain poorly understood. This study aims to unravel the tumor-immune interactions and signaling pathways driving primary resistance to ICIs in RCC.

Cancer stem cells (CSCs) play an important role in the development of triple-negative breast cancer (TNBC), including metastasis, invasion, tumorigenicity, and drug resistance. Moreover, non-CSCs can spontaneously transform into CSCs in special tumor microenvironments, thereby leading to poor prognosis or even failed treatments. Therefore, reversing tumor stem cells into normal tumor cells in a sustained-acting manner is a promising strategy.

In this research, a hollow mesoporous responsive nanomotor was proposed for enhanced photothermal/immunotherapy under near infrared (NIR) irradiation. HA-HMCuS/AS as the nanomotor composed of hollow mesoporous copper sulfide (HMCuS) loaded with artesunate (AS) and hyaluronic acid (HA) was utilized to induce the polarization of tumor-associated macrophages. At the beginning, ResNet18 deep learning model was utilized to predict the Brunauer-Emmett-Teller (BET) surface area of HMCuS based on the morphology data set which was obtained from our conventional research.

Rheumatoid arthritis (RA) is a prevalent autoimmune disease characterized by chronic inflammation and excessive proliferation of the synovium. Currently, treatment options focus on either reducing inflammation or inhibiting synovial hyperplasia. However, these modalities are unsatisfactory in achieving the desired therapeutic outcomes.
