Name: XR iPSC-Derived iMSC Differentiation Kit
Brand: XR

Description

Generating mesenchymal-like stem cells from induced pluripotent stem cells can be difficult to standardize across routine laboratory workflows. Variations in embryoid body formation, cell seeding, attachment, medium transitions, and passage timing may affect differentiation consistency and make it harder to obtain a uniform, expandable iMSC population.

XR iPSC-Derived iMSC Differentiation Kit is a staged culture system designed to support the differentiation of induced pluripotent stem cells into mesenchymal-like stem cells. The workflow uses three sequential media—iMSC Induction Medium A, Medium B, and Medium C—to guide cells through embryoid body formation, attachment, mesenchymal induction, and subsequent iMSC expansion.

This iMSC differentiation kit provides researchers with a structured iPSC-to-iMSC differentiation protocol intended to reduce workflow variability and support the generation of consistent iPSC-derived mesenchymal stem cell cultures. The resulting cells can be passaged after reaching approximately 90% confluence and may be evaluated by flow cytometry from passage 3 onward.

iPSC to iMSC Differentiation Workflow

The differentiation procedure begins with single-cell iPSC preparation and controlled embryoid body formation. Sequential medium changes then guide the developing cell aggregates through attachment, mesenchymal induction, and iMSC expansion.

Day 0

Seed single-cell iPSCs in a low-attachment 96-well U-bottom plate to form embryoid bodies.

Day 2

Transfer embryoid bodies to a low-attachment 6-well plate and begin culture with Medium A.

Day 5–8

Disrupt embryoid bodies, transfer cells to a coated adherent plate, and continue sequential induction.

Day 11+

Change to Medium C for iMSC culture and passage cells after they reach the recommended confluence.

Protocol Overview

Digest the iPSC culture into single cells and prepare a cell suspension at 150,000 cells/mL using iPSC culture medium supplemented with 10 μM Y-27632.
Add 15,000 cells to each well of a low-attachment 96-well U-bottom plate. Bring the final volume to 200 μL per well, centrifuge at 100 × g for 5 minutes, designate this as Day 0, and culture without disturbance for 48 hours.
On Day 2, transfer four to five embryoid bodies to each low-attachment 6-well plate and continue culture in iMSC Induction Medium A for 3 days.
On Day 5, collect the embryoid bodies in a 1.5 mL centrifuge tube. Mechanically disrupt the aggregates using a 10 μL pipette tip, resuspend them in Medium A, and seed them into a standard 6-well plate that has been prepared with an appropriate coating solution.
On Day 8, replace the culture medium with iMSC Induction Medium B and continue culture for 3 days.
On Day 11, replace the culture medium with iMSC Induction Medium C. Passage the cells when they reach approximately 90% confluence.
After the cells reach passage 3 or later, evaluate the cultured cell population using an appropriate flow cytometry characterization panel.

Important: Cell behavior may vary among iPSC lines. Researchers should confirm cell quality before induction and optimize coating, dissociation, feeding, and passage conditions for their specific cell line and laboratory workflow.

Performance Data

Morphological Changes During iMSC Differentiation

The product documentation presents representative images from multiple stages of the differentiation workflow. Compact embryoid bodies are visible at the initial stage, followed by aggregate attachment, outward cell migration, and the development of an adherent mesenchymal-like cell population during continued culture.

Flow Cytometry Characterization

Representative flow cytometry histograms are provided for passage 3 iMSC cultures. These data illustrate downstream cell characterization following the staged iPSC differentiation protocol. Individual laboratories should select and validate an appropriate marker panel for their intended research application.

Why Use an iPSC-Derived iMSC Workflow?

Primary mesenchymal stem cell research may be affected by limited tissue availability, donor-to-donor variability, and changes in proliferative behavior during extended culture. An iPSC-derived approach provides a renewable starting cell source and enables researchers to establish mesenchymal-like cultures from selected iPSC lines under a controlled laboratory workflow.

XR iPSC-Derived iMSC Differentiation Kit combines embryoid body formation with sequential induction media to organize the differentiation process into clearly defined stages. This format helps laboratories standardize medium transitions and culture timing while retaining the flexibility to validate cell identity and performance according to their own experimental requirements.

FAQ

What is the XR iPSC-Derived iMSC Differentiation Kit used for?

The kit is designed for the staged differentiation of induced pluripotent stem cells into mesenchymal-like stem cells. It supports embryoid body formation, adherent induction, and subsequent iMSC culture and expansion.

What is included in the iMSC differentiation kit?

The kit contains 30 mL of iMSC Induction Medium A, 20 mL of iMSC Induction Medium B, and 100 mL of iMSC Induction Medium C.

How does the iPSC-to-iMSC differentiation protocol work?

The workflow begins by forming embryoid bodies from single-cell iPSCs. The embryoid bodies are cultured with Medium A, mechanically disrupted and transferred to a coated adherent plate, followed by sequential culture with Medium B and Medium C.

How long does the initial iMSC induction process take?

The scheduled medium transitions extend from Day 0 through Day 11. After Day 11, the cells continue to grow in Medium C and may be passaged when they reach approximately 90% confluence.

How many iPSCs are seeded at the beginning of differentiation?

The supplied protocol uses a suspension concentration of 150,000 cells/mL and an initial seeding density of 15,000 cells per well in a low-attachment 96-well U-bottom plate.

Is Y-27632 used during the initial iPSC seeding step?

Yes. The protocol specifies preparation of the initial single-cell suspension in iPSC culture medium supplemented with 10 μM Y-27632.

Why are embryoid bodies used in this iMSC differentiation workflow?

Embryoid body formation provides an intermediate stage between the starting iPSC culture and the subsequent adherent mesenchymal induction steps. The supplied workflow begins with controlled aggregate formation before sequential exposure to the iMSC induction media.

When should the induced iMSC cultures be passaged?

After the Day 11 change to Medium C, the cells may be passaged when the culture reaches approximately 90% confluence.

When can iPSC-derived iMSCs be characterized by flow cytometry?

The product protocol recommends flow cytometry characterization after the cells have reached passage 3 or later. Researchers should select a marker panel appropriate for their laboratory and intended application.

Can this kit be used with every iPSC line without optimization?

Different iPSC lines may vary in growth, aggregate formation, attachment, and differentiation behavior. Cell-line-specific optimization and validation may therefore be required before routine use.

Is this product intended for clinical or therapeutic use?

No. XR iPSC-Derived iMSC Differentiation Kit is intended for research use only and is not intended for diagnostic, therapeutic, or direct clinical use.

For Research Use Only. Not for diagnostic or therapeutic use.
