C16-VVVAAAEEE
C16-VVVAAAEEE is a peptide amphiphile and biodegradable nanofiber scaffold that self-assembles into a hydrogel upon calcium ion triggering, enabling delivery of Sonic hedgehog protein to corpus cavernosum smooth muscle with prolonged release and without eliciting a significant immune response. C16-VVVAAAEEE is used in research on erectile dysfunction.

Description
In Vitro
C16‑VVVAAAEEE PA gel (100 mM; 1‑141 h) releases SHH protein in a time‑dependent manner, with 73% diffusion observed within 141 h in vitro[1].

-
Animal Model:Sprague Dawley rats (postnatal day 115-120, bilateral cavernous nerve resection)[1]
-
Dosage:20; 50; 100 µL (volume optimization); 50 µL (duration study); 10 mM final concentration
-
Administration:Injection into corpora cavernosa; single administration
-
Result:Visualized a highly brightened region of the penis at 20 µL.
Formed a gel uniformly throughout the entire penis at 50 µL.
Did not remain localized within the penis at 100 µL.
Remained localized completely in the penis when a silk tie was used.
Showed well dispersed fluorescence throughout both corpora cavernosa when injected distally.
Did not appear to reach all of the adjacent corpus cavernosum when injected proximally.
Formed a thin layer lining the sinusoidal spaces at 1 hour.
Was still abundant and clearly visible within the corpora cavernosa at 7 days.
Was observed as a nonspecific fluorescence indicating mostly degraded at 14 days.

3D Hydrogel Synthetic Scaffold Culture
3D hydrogel synthetic scaffold culture embeds cells, spheroids, organoids, or tissue fragments inside a hydrated crosslinked polymer network so that cells receive matrix and cell-cell cues in three dimensions rather than from a flat plastic surface. A literature-supported model protocol is PEG-4MAL hydrogel culture, in which four-arm maleimide-terminated PEG is functionalized with cysteine-containing adhesive peptides such as RGD and crosslinked with protease-degradable peptides such as GPQ-W; this creates a defined, modular scaffold that supports human organoid generation and culture. The readouts are scaffold-supported growth, morphology, lumen formation, budding, viability, proliferation, lineage-marker expression, and matrix-dependent expansion or differentiation; reported assays include transmitted-light imaging, immunofluorescence, in situ hybridization, qRT-PCR, and rheological characterization.
