A novel biodegradable polymer scaffold for in vitro growth of corneal epithelial cells

Indian Journal of Ophthalmology, 2022
The shortage of donor corneal tissue worldwide has led to extensive research for alternate corneal equivalents utilizing tissue engineering methods. We conducted experiments using Poly D, L lactic acid polymer along with a copolymer (Eudragit) in varying

Delivery of chemotherapeutic drugs in tumour cell-derived microparticles [PDF]

Nature Communications, 2012
Cellular microparticles are vesicular plasma membrane fragments with a diameter of 100-1,000 nanometres that are shed by cells in response to various physiological and artificial stimuli. Here we demonstrate that tumour cell-derived microparticles can be used as vectors to deliver chemotherapeutic drugs.

Microparticle alpha‐2‐macroglobulin enhances pro‐resolving responses and promotes survival in sepsis

EMBO Molecular Medicine, 2013
Incorporation of locally produced signaling molecules into cell‐derived vesicles may serve as an endogenous mediator delivery system. We recently reported that levels alpha‐2‐macroglobulin (A2MG)‐containing microparticles are elevated in plasma from ...

Cell-derived microparticles in haemostasis and vascular medicine

Thrombosis and Haemostasis, 2009
SummaryConsiderable interest for cell-derived microparticles has emerged, pointing out their essential role in haemostatic response and their potential as disease markers, but also their implication in a wide range of physiological and pathological processes. They derive from different cell types including platelets – the main source of microparticles –

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

A bioactive microparticle-loaded osteogenically enhanced bioprinted scaffold that permits sustained release of BMP-2

Materials Today Bio, 2023
Extrusion-based bioprinting technology is widely used for tissue regeneration and reconstruction. However, the method that uses only hydrogel as the bioink base material exhibits limited biofunctional properties and needs improvement to achieve the ...
