Mobilized Peripheral Blood Products

Human Tissues and Primary Cells

StemExpress is a life-science company dedicated to supporting researchers and clinicians globally by offering high-quality IRB-consented human tissues and primary cells from bone marrow, cord blood, peripheral blood (healthy or diseased), mobilized peripheral blood, and maternal blood. Samples are collected from our strategically located Stem Cell Collection Centers or within our vast network of partnering hospitals by our skilled procurement staff. Whole samples are sent directly to our clients or quickly processed to a primary cell population at one of our on-site GLP regulatory-compliant laboratories. We streamline the entire workflow, from donor recruitment all the way to shipping the final product, guaranteeing every sample arrives with the highest purity, viability, and quality researchers and clinicians need to ensure confidence in their results.

The StemExpress Advantage

Our goal is to provide consistent, high-quality products that enable you to easily navigate barriers, enhance quality, and drive success in your research and clinical projects.

The Right Donor

We are the only company in the industry that has multiple Stem Cell Collection Centers strategically located throughout the United States. These locations add donors of diverse demographics and backgrounds allowing ease in the selection of a specific DONOR for your research.

High-Quality Products

Our tissue collection, cell processing, cell isolation, and cell analysis methods are conducted using approved standard operating procedures (SOPs) performed by trained, qualified personnel in accordance with cGMP guidelines and with strict QUALITY assurance (QA) oversight and review.

Custom Products

We provide an end-to-end service whereby cells are collected, processed, isolated, and cryopreserved or shipped out fresh immediately after collection from one of our Collection Centers. This end-to-end service provides the ability to CUSTOMIZE each step of the procedure allowing you to obtain the exact product for your research.

Flexible Scheduling

Whether you are requesting tissue or primary cells, fresh or frozen, our staff works with you to find the right donor and schedule a day for collection that suits your schedule. We offer a variety of DELIVERY options including Same Day Delivery depending on your location.

What kind of demographic information is attached to StemExpress CoAs?

StemExpress is serious about donor confidentiality, and we strictly observe HIPAA regulations. Personal identifying information is removed from all samples and replaced with a nonspecific numeric identifier. If a study requires demographic information, we can provide researchers general identifiers like age, gender, weight, height, and minimal health history.

How to thaw StemExpress primary cells for optimal viability?

Primary cells are very sensitive to many aspects of the thawing procedure, such as heat, DMSO, agitation, and high centripetal forces. Obtaining high viability after thawing human primary cells can be difficult if not performed quickly and with good laboratory techniques. At StemExpress, our laboratory technicians have years of experience handling and thawing frozen human primary cells and have designed a procedure that will help you obtain the highest viability of your cells.
