Polylactic acid
Based on 1 Customer Validation
Polylactic acid (PLA) is a biodegradable and biocompatible polymer widely used as a carrier for drug delivery systems and a structural material for tissue engineering and medical implants. Polylactic acid acts as a controlled release matrix through the hydrolysis mechanism of ester bonds, gradually releasing the encapsulated drug and metabolizing to non-toxic lactic acid. Polylactic acid has adjustable degradation rate, mechanical properties and the ability to composite with other polymers, and can be used in local or systemic drug delivery, orthopedic fixation devices and 3D printed bone regeneration scaffolds.

In Vitro
Polylactic acid (PLA) showed more efficient release of 5-Fluorouracil (HY-90006) than pure polymer in electrospun hybrid nanofibers of 80:20 PLA/PCL ratio (20 g/L glucose). PLA microspheres (10 mg/mL; 35 days) achieved sustained release of Naltrexone (HY-76711) with a cumulative release rate of 67%. 3D-printed PLA/hydroxyapatite scaffolds (2 weeks in vivo) promoted osteoblast proliferation and bone formation in rabbit calvarial defects. PLA-based drug-eluting scaffolds (10 μg /cm2; 30 days) achieved controlled release of paclitaxel and reduced restenosis rate[1].

Protocols

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.
