Successful Cryoprotectant‐Free Vitrification of Honey Bee (Apis mellifera) Drone Sperm With Royal Jelly Supplemented Extender

Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.
Our results showed that adding a 1% royal jelly supplement to the cryoprotectant‐free vitrification media in the droplet method improves drone sperm quality parameters post‐warming. Our findings provide valuable insights into optimizing drone sperm preservation, contributing to the conservation of these vital pollinators.

Enhanced skin penetration of 10-hydroxy-2-decenoic acid via anionic polymer formulations and skin hydration modulation

Journal of Dermatologic Science and Cosmetic Technology
Background: The skin barrier function is primarily determined by the stratum corneum (SC), which restricts the penetration of active compounds. Royal jelly (RJ) contains 10-hydroxy-2-decenoic acid (10H2DA), an unsaturated fatty acid with potential ...

Fermented Royal Jelly Enriched With 10‐Hydroxydecanoic Acid and Its Potential for Enhancing Mucosal Immunity

Food Science &Nutrition, Volume 13, Issue 2, February 2025.
We isolated the Lactobacillus panisapium strain M1 from queen bee digestive tracts, capable of converting 10‐hydroxy‐2‐decenoic acid (10H2DA) in RJ to 10‐hydroxydecanoic acid (10HDAA). Through cultivation in protease‐treated RJ broth, we successfully produced fermented RJ (fRJ) containing significantly elevated 10HDAA levels compared to traditional RJ.

Dose-dependent immunomodulatory effects of 10-hydroxy-2-decenoic acid on human monocyte-derived dendritic cells

Journal of Functional Foods, 2013
The effect of 10-hydroxy-2-decenoic acid (10-HDA), the unique component of royal jelly, on maturation and functions of human monocyte-derived dendritic cells (MoDCs) in culture was investigated. It has been shown that 10-HDA, at concentrations higher than 500 μM, induces apoptosis of MoDCs.
