Shiny, New GF nanoparticle labeled hMSCs

Human Mesenchymal Stem Cells-Green Fluorescent Nanoparticle-labeled-These cells are generated by chemical transfection of CdSe/ZnS nanoparticles, 100 nm in diameter and show a strong fluorescent signal (Excitation maximum= 515 nm; Emission maximum= 520-550 nm) detectable by standard FITC filters.

Image obtaining using FITC filter on Olympus CKX41 microscope at 200 X equipped with a Retiga 2000 digital camera and Q-Capture software program. Scale bar is 25 micrometers. Fluorescent nanoparticles are less prevalent within the cytoplasm than earlier passages. Technical Information & Data.

They retain GFNP labeling through 3+ passages and can be differentiation into chondrogenic, adipogenic or osteogenic lineages. Excellent for regeneration, toxicity and related studies. Technical Information & Data.

Image obtaining using phase contrast Olympus CKX41 microscope at 100 X equipped with a Retiga 2000 digital camera and Q-Capture Pro software program. Scale bar is 25 micrometers. Note the presence of mineral deposits indicating differentiation into osteoblasts. Chondrogenic and adipogenic differentiation was also apparent.
