Cryopreservation of Pike Perch Sperm in Hatchery Conditions [PDF]
, 2008 Experiments were carried out on pike perch (Sander lucioperca L.) to find a method for stripping sperm without contamination by urine, to determine sperm concentration, and to fertilize large batches of eggs with cryopreserved sperm.

Lifespan‐Regulated CAR‐Macrophages from Myeloid Progenitors for Enhanced Colorectal Cancer Therapy
Advanced Science, EarlyView.Using a tamoxifen‐inducible Hoxb8 system, proliferative bone marrow progenitors can be generated, which are subsequently engineered with an anti‐CEA CAR construct containing a suicide gene (iCas9) and differentiated into CAR‐macrophages. This method facilitates scale up the production of CAR‐macrophages.

A Novel Cultivation System for Germ Cell Proliferation and Sustaining Whole Testicular Niche
Advanced Science, EarlyView.A hydrogel microneedle‐based system enables whole testicular cultivation, supporting spermatogonial proliferation and enhancing spermatogenesis in vitro. This ‘whole testicular spermatogonia pool’ (WTSP) significantly increases spermatid production and fertility potential in mice. This system also promotes spermatogonial expansion in human fetal testes,

Restoring NK Cell Cytotoxicity Post‐Cryopreservation via Synthetic Cells
Advanced Science, EarlyView.In this study, it is shown that 1‐day co‐culture with activated T cells or IL‐2‐presenting synthetic cells significantly enhances NK cell motility and cytotoxicity in 2D and 3D. Notably, synthetic cells restore the impaired cytotoxic function of cryopreserved NK and CAR‐NK cells in 3D.

A Bayesian Approach to Optimizing Stem Cell Cryopreservation protocols
, 2014 Cryopreservation is beset with the challenge of protocol alignment across a wide range of cell types and process variables. By taking a cross-sectional assessment of previously published cryopreservation data (sample means and standard errors) as ...

ACSS2/AATF Drives Soluble FasL‐Mediated CD8+ T Cell Apoptosis in Pancreatic Neuroendocrine Tumors
Advanced Science, EarlyView.This study unveils that ACSS2‐driven acetate metabolism fuels histone pan‐acetylation in pancreatic neuroendocrine tumors (PNETs), remodeling the epigenetic landscape. The ACSS2/AATF axis transcriptionally activates soluble FasL (sFasL), which engages Fas receptors on infiltrating CD8+ T cells to trigger caspase‐8/3‐mediated apoptosis.
