BIOMIMESYS® Adipose tissue represents a new
generation of mimetic Hydroscaffold™ for 3D
culture of adipocyte and adipocyte-like cells.
Available in a ready-to-use format, it enables the
culture of adipocytes and adipocyte-like cells under
physiological conditions that are representative of
the microenvironment found in adipose tissue. The
highly porous nature of the scaffold allows the rapid
uptake of nutrients, oxygen, etc. into the cells to
create a reproducible study model for all
downstream analyses used with 3D adipocyte
cultures.

components (Collagens type I and VI and cell binding domain of Fibronectin), BIOMIMESYS® Adipose tissue
Hydroscaffold™ for 3D adipocyte-like cells is thus an ideal study model because it is:
Highly porous for the simple extraction of RNA and proteins
Translucent for direct visualization of cells
Representative of the adipocytes microenvironment in terms of cell-cell interactions, matrix
composition and cell-matrix interactions
HYALURONIC ACID (HA) + Collagen I & VI system, major component of the adipocyte extracellular
matrix (ECM), where it plays an IMPORTANT ROLE in connective tissue.
HA-based scaffolds are formed by HA-grafted RGDS + Collagen I & VI system crosslinking HA with
ADH to form reticulated chains.
High molecular weight HA is made from Gram+bacteria, which makes it reproducible.

o Porosity: 70-170um
o Rheology: Young’s modulus: E= 0.45 ± 0.05kPa
o Swelling ratio = 60 ± 10g/g
ADIPOCYTES
The major role of the adipocyte is to store (lipogenesis) and release fat
(lipolysis), an energy reservoir in the body. The phenomena of
lipogenesis and lipolysis can be controlled, among other things, by the
secretion of adipokines from adipose tissue. This secretion can have
autocrine, paracrine or endocrine effects. Deregulation of lipolytic
mechanisms plays a role in many diseases (obesity, diabetes, etc.).
LIPOGENESIS – AN IMPORTANT ROLE OF ADIPOCYTES
Lipogenesis is the process of storing the free fatty acids (FAs) in the form of triglycerides (TGs) within droplets
leading to mature adipocytes. These mature adipocytes are composed of a single lipid vesicle, a nucleus
present at the periphery of the cell and a very thin cytoplasm. If necessary, TGs are hydrolyzed by lipolysis
and glycerol is released (1).

Adipogenesis is a phenomenon characterized by chronological changes in the expression of many genes, in
two stages:
1) Proliferation of preadipocytes, examples of early markers:
Lipoprotein lipase: LPL
C / EBPα
PPARγ2
FABP-4
2) Differentiation: increased
lipogenesis and insulin sensitivity,
markers amongst others:
Perilipin
ATPcitratelysase
Malic enzyme
AcetylCoAcarboxylase
LHS
Glut4 …
CELL CULTURE MIMICKING THE FAT CELL MICROENVIRONMENT
The cell culture capable of mimicking, in vitro, the development of adipose tissue in vivo, is an experimental
field for the study of physiology and function of adipocyte. This study was originally submitted to
investigative challenges on animals or on isolated cells. New cell models also allow the evaluation and drug
screening of therapeutic interest.
Adipocytes differentiated in 2D do not express adipocyte genes in the same way as adipocytes in vivo. The
confluence found in 2D and the lack of cell/cell or cell/extracellular matrix interactions results in a
heterogeneous culture, with a population of undifferentiated adipocytes (fibroblast shape). This model
seems less predictive in the study of diseases such as diabetes or obesity (1).
Cristancho (2), Dalby (3) and Mc Beath (4) have independently shown that a spheroidal cell shape,
accompanied by a physiological composition of the extracellular environment, allows to strongly induce the
differentiation of preadipocytes.
On this basis, HCS Pharma has developed a 3D hydroscaffold, whose 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 Hydroscaffold™.

In order to demonstrate the induction of adipogenesis by 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.

READY TO USE
BIOMIMESYS® is EASY to handle & 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.
