Random, Unannounced Testing
Vials are tested without warning. If a lab's "validated" batch fails, we don't distribute their products.
Why We're Different
Our Unique Approach to Quality
Our Commitment to Excellence
We believe in empowering researchers to achieve breakthroughs. Whether exploring new frontiers in regenerative science or validating innovative methodologies, MethusBio is your trusted partner for reliable and ethically sourced biologics.
Quality Assured
Validated Results
Industry Leading
Our Commitment
Real Post-Thaw Viability
Viability is verified after freezing and shipping, so you see the real performance you'll get.
Licensing & Due Diligence
We check every lab's paperwork, equipment, and compliance, so you don't have to.
Proper Cold Chain Logistics
We insist on correct LN2 shipping temperatures. If they can't handle it, they won't handle your cells.

FAQs
Common Questions About Our Products
- Independent Post-Thaw Viability Testing – Many labs report viability pre-freeze, but post-thaw performance can be drastically different. We ensure accurate, independent testing.
- Flow Cytometry & Biomarker Validation – Labs use internal testing, but without incentives to be honest. We verify passage number, cell phenotype, and viability with third-party flow cytometry.
- Cold Chain Tracking & Compliance – Handling mistakes and temperature fluctuations degrade cells. We enforce continuous temperature monitoring and ensure proper logistics.
- Risk Mitigation for Clinics & Researchers Internationally – Stem cell compliance is complex, and improper sourcing has serious legal and safety risks. We help clients navigate these challenges while maintaining ethical sourcing.
Stem cells are shipped cryopreserved in liquid nitrogen vapor phase (≤−150°C)
using a validated dry shipper. This maintains cell viability during transit.
Package includes:
- Cryobox or cryobag
- Dry shipper with temp logger
- Shipping manifest
We use liquid nitrogen (LN2) to keep hUC-MSCs well below the glass phase, or
vitrification transition zone, at −150°C, preventing ice crystal formation and
metabolic activity. This preserves cell viability, potency, and regulatory
compliance during storage and shipping.
Passage number refers to how many times a cell culture has been subcultured or
transferred to a new vessel during laboratory expansion. Each time the cells are
split and replated to continue growing, the passage number increases (e.g., P0,
P1, P2, etc.).
This number matters because it reflects the replicative age of the cells. Over time, high passage numbers can lead to changes in cell behavior, function, and genetic stability. For therapeutic and research use, maintaining a low passage number ensures high-quality, functional, and consistent cells.

Early-Passage MSCs (P1–P4):
- High proliferation potential
- Low senescence
- Strong differentiation capacity
- Potent immunomodulatory function
Mid-Passage MSCs (P5–P6):
- Decline in proliferation
- Emerging senescence markers
- Reduction in therapeutic potency
Late-Passage MSCs (P7+):
- Reduced differentiation ability
- Weakened immunomodulatory effects
- Increased risk of genetic instability
