Aim: To detect the differentiation effects of retinal cells or extracts on bone marrow-derived mesenchymal stem cells (BMSC).

Methods: Human fetal BMSC were previously labelled by carboxyfluorescein succinimidyl ester (CFSE), and co-cultured with retinal pigment epithelial (RPE) cells which were pre-treated with ultraviolet irradiation at a ratio of 1:1 to induce the differentiation of BMSC for up to 14 days. In some assays, a retinal extract of bovine retinal extract (BRE) was added to detect the potential effects of retinal component on the differentiation of BMSC. In addition, Neuron-specific enolase (NSE), Nestin and Glial fibrillary acidic protein (GFAP) immunostaining were performed to determine the characteristics of BMSC.

Results: The results indicated that by co-cultured with RPE cells, fetal BMSC were differentiated into neural-like cells expressing special neuronal markers Nestin, GFAP and NSE. And the expression of these markers was obviously increased by BRE.

Conclusion: Retina derived cells and extracts can induce the differentiation of BMSC into neural-like cells.

Tuft cells transdifferentiate to neural-like progenitor cells in the progression of pancreatic cancer.

Dev Cell

December 2024

Department of Surgery, Henry Ford Health, Detroit, MI, USA; Department of Pharmacology and Toxicology, Michigan State University, Lansing, MI, USA. Electronic address:

Pancreatic ductal adenocarcinoma (PDA) is partly initiated through the transdifferentiation of acinar cells to metaplasia, which progresses to neoplasia and cancer. Tuft cells (TCs) are chemosensory cells not found in the normal pancreas but arise in cancer precursor lesions and diminish during progression to carcinoma. These metaplastic TCs (mTCs) suppress tumor progression through communication with the tumor microenvironment, but their fate during progression is unknown.

The mandate for this special issue of Hippocampus was to provide a few examples of one's own work in a relatively personal context. Accordingly, I will discuss some of my own work here, but will also provide a broader arc of ideas and discoveries within which the efforts of myself and many others have taken place. This history begins with the associationists, who proposed that the human mind could be understood, in part, as a compounding of simple associations between contiguously occurring items and events.

Article Synopsis
  • Biliary tract cancers show strong resistance to treatments, and effective therapies for these advanced cases are currently limited.
  • A clinical trial combined DKN-01 and nivolumab to see if they could help patients with advanced biliary tract cancer, but no positive results were found.
  • Researchers analyzed tissue samples to identify different cell types that contribute to the cancer's resistance, discovering new immune and malignant cell states that could inform future treatment strategies.

Varicella-zoster virus recapitulates its immune evasive behaviour in matured hiPSC-derived neurospheroids.

Front Immunol

Article Synopsis
  • * The study analyzed how human neural-like cells (neurospheroids) respond to VZV infection compared to Sendai virus (SeV), finding that SeV triggers a strong immune response while VZV appears to evade detection.
  • * The research indicates that VZV not only avoids activating the immune system but also disrupts cellular integrity and prompts stress response mechanisms in the long term.

Background: Reduction of adult hippocampal neurogenesis is an early critical event in Alzheimer's disease (AD), contributing to progressive memory loss and cognitive decline. Reduced levels of the nucleoporin 153 (Nup153), a key epigenetic regulator of NSC stemness, characterize the neural stem cells isolated from a mouse model of AD (3×Tg) (AD-NSCs) and determine their altered plasticity and gene expression.

Methods: Nup153-regulated mechanisms contributing to NSC function were investigated: (1) in cultured NSCs isolated from AD and wild type (WT) mice by proteomics; (2) in vivo by lentiviral-mediated delivery of Nup153 or GFP in the hippocampus of AD and control mice analyzing neurogenesis and cognitive function; (3) in human iPSC-derived brain organoids obtained from AD patients and control subjects as a model of neurodevelopment.
