How many donors are pooled to create the pooled human cells?

Lonza is offering the following primary cells from single donors and from pooled donors:HUVEC (human umbilical vein endothelial cells)NHEK-neo (human epidermal keratinocytes)HMVEC-dNeo (human microvascular endothelial cells, dermal, neonatal)When...

Are Lonzas Smooth Muscle Cells contractile or synthetic?

Lonza’s Smooth Muscle Cells are synthetic in their proliferating state. As the cells begin to differentiate, they become contractile.

When would be the optimal time to perform experiments post osteogenic differentiation for human mesenchymal stem cells?

Once the cells have differentiated and started laying down bone matrix, we recommend assaying the cells immediately. If cells begin to delaminate (peel of the culture plate in layers), this would indicate that the cells are embedded in the calcium...

Can hydrocortisone be excluded from the Clonetics® BulletKit® when culturing cells? What is the purpose of hydrocortisone in the culture media?

Hydrocortisone is used for at least two purposes in Lonza’s primary cell culture media. Hydrocortisone (in combination with low serum concentrations) will inhibit the takeover of the culture by fibroblasts which may be present in small numbers from...

For cultivation of Smooth Muscle Cells - Can the insulin be left out of the SmGM-2 Media?

Yes, insulin can be left out of the SmGM™-2 media for as long as 1-3 passages.Insulin is beneficial to the cells for long term growth (ie. 4 - 5 passages), however smooth muscle cells do survive quite well short term without insulin.Insulin is not a...

Can heparin be excluded when culturing endothelial cells? What is the purpose of heparin in the endothelial cell culture media?

Heparin is added because it creates a better environment for FGF binding. Removing heparin for one passage should not have a noticeable effect, however for successive passaging, effects on proliferation may become more significant. It should be noted...

Are the human mesenchymal stem cells (PT-2501) more prone to become differentiated down one lineage over the other?

MSCs are prone to differentiate down an adipogenic lineage and some may accumulate lipids in the growth media or the differentiation kits other than the adipogenic differentiation media. MSCs are especially prone to spontaneous adipogenic...

Where are Lonzas Normal Human Osteoblasts (NHOst) cells isolated from?

Lonza’s Normal Human Osteoblasts (NHOst) are isolated by explant, and the tissue is from the spongy section of the bone head of the ribs, femur, or tibia.

When is the ideal time to study Lonzas Human Knee Articular Chondrocytes (NHAC-kn) after re-differentiation?

For maximum re-differentiation and therefore maximum collagen production, Lonza’s Human Knee Articular Chondrocytes should be studied within the first passage after re-differentiation. Serial expansion in monolayer culture after re-differentiation...

What is the primary differentiation reagent for chondrogenic differentiation of mesenchymal stem cells?

Lonza recommends the addition of TGF-B3 (PT-4124) to the Chondrogenic Differentiation Media (PT-3003) to promote chondrogenic differentiation of MSCs. Please see the MSC differenation protocol for complete details on differentiating MSCs down a...
