Human mesenchymal stem cells (MSCs) are multipotent adult stem cells, which have the capacity for multi-lineage differentiation, giving rise to a variety of mesenchymal phenotypes such as osteoblasts (bone), adipocytes (fat), and chondrocytes (cartilage). Mesenchymal stem cells usually reside in the bone marrow stroma, but have also been found in adipose, liver, spleen, peripheral blood, umbilical cord blood, and other mesenchymal tissues. Due to their capacity for self-renewal over long periods of time and the ability to differentiate into specialized cells, interest in understanding the biology of MSC cultures has increased, especially for their therapeutic potential for a variety of diseases. We offer a broad range of tools and technologies to culture mesenchymal stem cells including low passage MSC lines from various tissues, optimized expansion and differentiation media and a broad range or MSC related antibodies and cellular dyes.

A Superior Alternative to FBS for Human MSC Cultures
With the increasing interest and utilization of human cellular therapy, PLTMax Human Platelet Lysate meets the need for a research grade cell culture supplement that is human derived, serum-free, and cost effective for human mesenchymal stem cell cultures.
Features and Benefits:
Figure 3. PLTMax supports better growth of hMSCs than DMEM + FBSA: Growth of hMSCs cultured in αMEM supplemented with 5 % HPL or 10 % FBS as compared to DMEM + 10 % FBS over 4 passages in T150 flasks, or B: in duplicate 125 mL spinner flasks f or 7 days, demonstrating enhanced growth in αMEM + HPL
For stem cell applications where nutrient-rich FBS is required, we now offer mesenchymal stem cell qualified fetal bovine serum (ES-020-B). To reduce lot-to-lot variability, each lot of FBS is extensively screened and qualified to support human MSC cultures using a rigorous clonal growth assay.
Product Focus: OsteoMAX-XF™ Differentiation Medium
OsteoMAX-XF™ Differentiation Medium is specially formulated to readily differentiate human mesenchymal stem cells into mature osteocytes as assessed by alizarin red and alkaline phosphatase staining. This proprietary formulation was developed using Plasticell’s CombiCult™, a patented, bead-based, combinatorial technology specially developed for discovery of novel stem cell differentiation protocols.
Features and Benefits
“OsteoMAX-XF produces tissue of impressive osteogenic potential, including key bone-specific and mineralization markers. We found we could rapidly fabricate functional, fully human tissue derived from MSCs and the ECM proteins they produce using the NovoGen MMX 3D-Bioprinter”

Mesenchymal Stem Cell Related Stains and Dyes
The Human Mesenchymal Stem Cell Characterization Kit contains a panel of validated positive and negative selection markers for the characterization of the mesenchymal stem cell population in human samples. The kit contains positive antibodies directed against CD44, CD90, STRO-1, and CD146. In addition, two specific hematopoietic antibodies CD14 and CD19.
