What are 3T3-L1 adipocytes?

What are 3T3-L1 adipocytes?

3T3-L1 is a cell line derived from (mouse) 3T3 cells that is used in biological research on adipose tissue. 3T3-L1 cells have a fibroblast-like morphology, but, under appropriate conditions, the cells differentiate into an adipocyte-like phenotype.

How can you tell the difference between 3T3 and L1 cells?

Differentiation of 3T3-L1 cells into adipocyte-like cells

1. Seed cells in a six-well plate at a density of 3×103 cells per cm2.
2. Grow cells in DMEM until a confluency of 70% is reached, changing the medium every 2–3 days.
3. To initiate differentiation, remove DMEM and add 2–3 mL MDI induction medium per well (Day 0).

What is adipogenic differentiation?

Adipogenesis is a tightly regulated cellular differentiation process, in which mesenchymal stem cells committing to preadipocytes and preadipocytes differentiating into adipocytes.

What are 3T3 L1 fibroblasts?

3T3‐L1 fibroblasts are a continuous substrain of 3T3 (Swiss albino) developed through clonal isolation (CL‐173, ATCC). The cells undergo a preadipose to adipose‐like conversion as they progress from a rapidly dividing to a confluent and contact inhibited state.

What are 3T3 cells used for?

Reversible immortalization: NIH 3T3 cells were used as a control in a study of reversible immortalization of mammalian cells using an oncogene. Scientists were able to determine that the oncogene provided immortalization, and then, once excised, cells reverted to their pre-immortalization characteristics.

What is a cell line in cell culture?

Cell line is a general term that applies to a defined population of cells that can be maintained in culture for an extended period of time, retaining stability of certain phenotypes and functions. Cell lines are usually clonal, meaning that the entire population originated from a single common ancestor cell.

What is the function of adipocyte?

The Adipocyte as Functional Endocrine Cell The classical function of the adipocyte is as a calorie storage system accepting chemical energy in the form of glucose and fatty acid from the blood and converting these metabolites to TG for storage during fed conditions via lipogenesis.

What organ system is adipose tissue in?

the integumentary system
Adipose tissue is primarily located beneath the skin, but is also found around internal organs. In the integumentary system, which includes the skin, it accumulates in the deepest level, the subcutaneous layer, providing insulation from heat and cold. Around organs, it provides protective padding.

How long is Adipogenesis?

Directed differentiation of ES cells into the adipose lineage can be achieved over a 3-week period. Although adipocyte differentiation is initiated early in the development of cultured ES cells, TSHR up-regulation is precisely correlated with terminal differentiation of those adipocytes.

What is a pre adipocyte?

Pre-Adipocytes are derived from mature adipocytes that have been dedifferentiated, and are cryopreserved to ensure optimal phenotype and the highest viability and plating efficiency. Human Pre-Adipocytes can be expanded in an undifferentiated state for future differentiation to mature Adipocytes.

What are MC3T3 E1 cells?

The osteoblastic cell line MC3T3-E1 has been established from a C57BL/6 mouse calvaria and selected on the basis of high alkaline phosphatase (ALP) activity in the resting state. Cells have the capacity to differentiate into osteoblasts and osteocytes and have been demonstrated to form calcified bone tissue in vitro.
