Description of Reprogramming Services
CCRM performs reprogramming of somatic cell types to induced pluripotent stem cells (iPSCs) for clients in both academia and industry. We specialize in non-integrative strategies, including Sendai virus infection and episomal transfection of the four reprogramming factors, Oct4, Sox2, Klf4 and c-Myc. We are able to reprogram both fibroblasts and cells isolated from peripheral or cord blood samples. We accept cryopreserved vials of low passage primary fibroblasts, freshly collected blood samples or frozen buffy coat.
Reprogramming using alternative methods, or using alternative cell types may be possible. Please contact us to discuss your project further.
The Table below describes an example of the Reprogramming and Characterization Services that we provide:

|
|
Activity |
Description |
|
Stage 1 |
Parental Cell Expansion, Banking and Mycoplasma Testing |
Cryopreserved fibroblasts are thawed. If the culture is mycoplasma negative, cells are expanded to obtain a sufficient number for reprogramming. Likewise, if necessary, target cells are isolated from fresh blood samples and expanded in culture until a sufficient number is obtained for reprogramming. |
|
Stage 2 |
Transduction of Reprogramming Factors |
hOct4, hSox2, hKlf4 and hc-Myc are introduced using Sendai virus or episomal transfection methods or retro/lenti viruses. |
|
Stage 3 |
Reprogramming Time Course |
Seven days following induction, reprogramming cells are re-seeded onto 10-cm dishes. hESC medium is exchanged daily until approximately day 28, until authenticated (identified using in-house established and validated criteria) colonies are ready to be picked. |
|
Stage 4 |
Picking Authentic Colonies |
Authenticated colonies are identified, cleaned and picked into individual feeder-coated wells. |
|
Stage 5 |
Expansion of Induced Pluripotent Cell Lines |
iPSC lines are expanded under the preferred culture conditions to establish five vials of cryopreserved cells for each line. |
|
Stage 6 |
Characterization of Induced Pluripotent Cell Lines |
The following characterization assays will be performed and provided in a report:

A final service report will be prepared that includes all of the protocols used, and data collected throughout, iPSC manufacturing.
The cost to reprogram a sample is $10,000 CAD. This includes delivery of three karyotyped and fully characterized iPSC lines, produced as outlined in Tables 1 and 2. Investigators affiliated with CCRM’s member institutions are eligible for subsidies totaling $2,500 CAD/iPSC sample derived.
Every research project is different. Customized projects may have additional costs. Please contact us to discuss your specific requirements so that we can help you design a successful experiment.

“Thank you for organizing an amazing workshop. I learned all I needed to know about iPS cells.” – 2012 University of Calgary trainee
CCRM hosts a Human Induced Pluripotent Stem Cell (HiPSC) Workshop to teach participants how to apply the processes involved in the production and maintenance of iPSCs, and gain a strong foundation in standardized validation and characterization methods to ensure quality stem cell lines are being produced.
The workshop is also an excellent opportunity for participants to build a national and international network of colleagues whose interests are in iPSC technology. During the workshop, you will learn the following:
- Theory of iPSC production and underlying technical methodologies applied to achieve reprogramming.
- Hands-on basic cell culture for human ESCs, iPSCs and primary fibroblast lines, including media preparation, colony picking and expansion, cryopreservation and revival.
- Hands-on induction of fibroblasts and blood cells using various transgene delivery methods.
- Hands-on identification of emergent iPSC colonies and their isolation.
- Characterization of established iPSCs via immunostaining and quantitative PCR, as well as high-throughput methods using flow cytometry.
- Differentiation of iPSCs along desired embryonic lineages.
“I wanted to thank you all for putting together the iPSC workshop - it was a great introduction to working with iPSCs, and I enjoyed the hands on practice. The preparatory lecture and your guidance during the lab time was invaluable.” – 2012 workshop participant.
