Descripción general
Además, el RA y otros retinoides pueden inhibir también la proliferación celular y estimular la actividad tirosinasa en una línea celular del melanoma humano,[4] a la vez que también inhiben la adhesión célula-sustrato y la motilidad en los melanocitos. El ATRA desempeña un papel vital en la formación del sistema vascular de los mamíferos. Específicamente, regula la proliferación de las células endoteliales y la remodelación vascular a lo largo de la angiogénesis tisular.[2]
Aplicación
- El ácido retinoico (RA) se ha utilizado para la diferenciación de las células madre embrionarias en motoneuronas.[5]
- Se ha utilizado para la la diferenciación del ectodermo de Xenopus en páncreas.[6]
- También se ha utilizado para estudiar la regulación epigenética por el RARα (receptor del ácido retinoico α).[7]
- También se ha utilizado para estudiar la señalización de la transición de proespermatogonia en espermatogonia por el RA.[8]

Can I dissolve retinoic acid in PEG 1500?
1 answer-
This compound has not been tested for solubility in PEG 1500. Various sources report that retinoic acid is slightly soluble in PEG 400. This information has not been validated. Other solvents include DMSO at 25 mg/mL, ethanol at 10 mg/mL, DMF at 20 mg/mL, chloroform at 40 mg/mL, and acetone at 30 mg/mL. Please see the link below to review the product datasheet which includes additional information on solubility and stability:

After dissolving the Retinoic acid in DMSO to create a 20mM stock concentration, I diluted it 1,000 times to achieve a final concentration of 20μM. Crystals have formed in the cell culture dishes where I added this solution but not in the DMSO vehicle dishes. Could there be an issue with this lot, or are there other reasons why crystals are forming?
1 answer-
The product R2625 is soluble at around 40 mg/ml in DMSO, yielding a clear solution. Although the stock seems fine, adding the DMSO solution to the media causes crystals to form. This is common when diluting a high-concentration stock made in organic solvents into aqueous media. To address this, try reducing the stock solution to lower concentrations in DMSO multiple times before adding it to the media to ensure an adequate organic environment around the product. There is nothing wrong with the product itself.

Can I reconstitute retinoic acid in water instead of chlorofrom? What is its solubility in water?
1 answer-
The solubility of each Lot of Retinoic Acid is tested in chloroform as shown on the specification sheet.
https://www.sigmaaldrich.com/specification-sheets/150/073/R2625-BULK________SIGMA____.pdfThe Product Information Sheet provides additional solvents, however, water is not recommended:
"RA is more sensitive to light, heat, and air in solution. It is practically insoluble in water; slightly soluble in alcohol and chloroform, sparingly soluble in ether, and soluble in methylene chloride. RA is soluble at about 40 mg/ml in DMSO and at about 2.7 mg/ml in 95% ethanol (vortexing may be needed). "
