BIOMIMESYS® Adipose Tissue is a Hyaluronic acid (HA) based scaffold 3D cell culture model. This groundbreaking 3D cell culture technology associates the behavior of a solid scaffold and of a hydrogel, which we call “Hydroscaffold”. The Hydroscaffold’s composition and mechanical properties can mimics the microenvironment of adipose tissue. It is proven to provide better in vitro/in vivo correlation and cell longevity than 2D models.
Mimics the microenvironment of adipose tissue
BIOMIMESYS® Adipose Tissue composition and organization are similar to in vivo adipose tissue by including collagens I, VI and fibronectin (RGDS pattern) in a cross-linked hyaluronic acid gel.
In order to demonstrate the induction of adipogenesis by the HCS Pharma hydroscaffold, BIOMIMESYS® Adipose tissue, various tests were performed on two cell types: 3T3-L1 and Human White Preadipocyte (HWP) according to the following culture protocol.
Protocol: as in 2D culture, seeding and differentiation steps are induced from day 0 (for HWP and 3T3-L1) until complete maturation.
Figure: A and B: Adipocyte schematic morphology in vivo.
C and D: Light-microscopy images of adipocyte differentiated from preadipocyte HWP (Human white preadipocytes) at 7 days after seeded. HWP cultured in 2D exhibited a fibroblastic appearance (C), whereas in BIOMIMESYS® Adipocyte, it was resembling morphology of mature adipocytes in vivo, showing the establishment of their principal function, fat accumulation, resulting in the presence of vesicles (D).
E and F : SEM images of 3T3-L1 (murine preadipocytes) at day 7 (E) and HWP at day 14 (F), both were cultured in BIOMIMESYS® Adipocyte. In the hydroscaffold, adipocytes formed aggregates which increased in size over time.
Better differentiation and cell longevity
BIOMIMESYS® Adipose Tissue is dedicated to the culture of adipocytes: compared to 2D culture, primary human pre-adipocytes in BIOMIMESYS® Adipose Tissue (3D) showed optimal differentiation into adipocytes, and their functionality (such as lipid storage in a single large vacuole) was maintained until 28 days.
For a better in vitro/in vivo correlation
Figure 2: Lipid accumulation in 3T3-L1 with or with Retinoic acid, compared to 2D cultures (n=3, two-ways ANOVA statistics with Tukey post-hoc ; * : p<0,05 ; ** : p<0,01 ; *** : p<0,001)
To quantify the inhibition of lipogenesis, human pre-adipocytes and 3T3-L1 cells cultured in BIOMIMESYS® Adipose tissue and in 2D culture are treated with Retinoic acid, a well-known regulator. Lipid accumulation is measured using the AdipoRed ™ kit, normalized by DNA level.
As low as 1μM of Retinoic acid led to a significant lipids accumulation inhibition in 2D, whereas at least 5μM of this molecule was needed to significantly inhibit the lipogenesis of adipocytes grown in BIOMIMESYS® Adipose tissue.
Ready to Use
BIOMIMESYS® Adipose Tissue is EASY & READY TO USE. Upon receiving the vacuum sealed 96-well plate open it (under a hood) and add the cells directly on top of the matrix. Changing the culture medium is easy as well. To remove medium, simply draw the medium with a pipette between the matrix and the edge of the well. To refresh the medium, place fresh medium onto the surface of the matrix.
