Despite promising preclinical outcomes in animal models, a number of challenges remain for human clinical use. In particular, expanding a large number of endothelial progenitor cells (EPCs) in vitro in the absence of animal-derived products is the most critical hurdle remaining to be overcome to ensure the safety and efficiency of human therapy. To develop in vitro culture conditions for EPCs d...

Distinguishing cutaneous infection from sterile inflammation is a diagnostic challenge and currently relies upon subjective interpretation of clinical parameters, microbiological data, and nonspecific imaging. Assessing characteristic variations in leukocytic infiltration may provide more specific information. In this study, we demonstrate that homing of systemically administered monocytes tagg...

PURPOSE To assess the potential of an MRI gene reporter based on the ferritin receptor Timd2 (T-cell immunoglobulin and mucin domain containing protein 2), using T1- and T2-weighted imaging. METHODS Pellets of cells that had been modified to express the Timd2 transgene, and incubated with either iron-loaded or manganese-loaded ferritin, were imaged using T1- and T2-weighted MRI. Mice were als...

A new microparticle-based delivery system was synthesized from reactive oxygen species (ROS)-responsive poly(propylene sulfide) (PPS) and tested for "on demand" antioxidant therapy. PPS is hydrophobic but undergoes a phase change to become hydrophilic upon oxidation and thus provides a useful platform for ROS-demanded drug release. This platform was tested for delivery of the promising anti-inf...

The aim of this investigation was to design and develop nanoemulsions (NEs) as novel ophthalmic delivery systems for brinzolamide (BZD). Phase behavior of quaternary systems composed of triacetin and CapryolTM 90 (selected oils, screened through the solubility studies), various surfactants (namely, Cremophor RH 40, Brij 35, Labrasol and tyloxapol), Transcutol P (as co-surfactant) an...

this review article investigates a comprehensive description of the factors, methods, strategies, approaches and prerequisites influencing in vitro micropaopagation and the amount of their use across the world. the findings presented here are the results of the study of several hundred papers published all over the world. tissue culture techniques are routinely used for micropropagation. enhanc...

Multicellular spheroids are an established system for three-dimensional cell culture. Spheroids are typically generated using hanging drop or non-adherent culture; however, an emerging technique is to use magnetic levitation. Herein, mesenchymal stem cell spheroids were generated using magnetic nanoparticles and subsequently cultured within a type I collagen gel, with a view towards developing ...

INTRODUCTION Rat mesenchymal stem cells (MSCs) represent a small portion of the cells in the stromal compartment of bone marrow and have the potential to differentiate into new blood vessel and other tissues. MSCs transplantation in tissues from critical limb ischemia model in rat may represent a therapeutic applications of vascular regeneration. AIM The aim of this study was to isolate with ...

The aim of this study was to address one of the major challenges of the actual era of nanomedicine namely, the bioavailability of poorly water soluble drugs such as Silymarin. We developed new, biodegradable, and biocompatible nanosized shuttles for Silymarin targeted delivery in colon-cancer cells. The design of these 100 nm sized carrier nanoparticles was based on natural polymers and their b...
