Case Study
To investigate whether partial reprogramming exerts beneficial effects on Alzheimer's disease, this study used APP/PS1 mice, a classic AD model, and performed OSK partial reprogramming on engram cells in the DG and mPFC brain regions. Key indicators, including the expression of Prox1, Ctip2, and LaminB1, were detected, and spatial learning and memory were evaluated using the Morris water maze. The results showed that OSK reprogramming upregulated the expression of these markers and effectively restored hippocampal learning strategies and spatial memory in a memory-specific manner. In conclusion, partial OSK reprogramming targeting engram cells can rescue spatial learning and memory deficits in APP/PS1 mice.

FAQs
Q: Can your factors be used for in vivo reprogramming in the brain?
A: Yes, we offer specialized viral vector formulations, including AAVs, that are optimized for CNS delivery and have been used in recent studies targeting specific neural circuits like engram cells.
Q: What makes your "Chemical Time Machine" different from standard OSKM methods?
A: Our small-molecule cocktails offer a "footprint-free" approach. They are tunable, safer regarding tumorigenic risk, and allow for partial rejuvenation where the cell retains its original identity while resetting its metabolic and epigenetic clock.
Q: Do you provide support for "Aging" signature preservation?
A: Yes. Our Direct Conversion factors bypass the pluripotent stage, allowing you to create neurons that retain the donor's age-related epigenetic markers, essential for modeling late-onset diseases.
Q: What is the purity level of your recombinant reprogramming proteins?
A: We provide proteins at >95% purity as determined by SDS-PAGE and HPLC, ensuring minimal interference in sensitive cell culture environments.
Q: Are custom factor combinations available for rare neuronal subtypes?
A: Yes, we can design and prepare custom sets for specialized cells, such as dopaminergic, serotonergic, or motor neurons, based on your specific gene expression requirements.
Creative Biolabs provides a full-scale portfolio of services, including the design, synthesis, and validation of transcription factors, neural-specific conversion factors, and anti-aging chemical modulators. We empower your research by providing the highest quality tools for cellular engineering and regenerative medicine.
