Obesity and its comorbidity incidence have increased worldwide during the past 10 years. In consequence, researchers have drawn their attention to the understanding of adipocyte differentiation. Several cellular model systems have been established; however no efficient protocol could be developed so far to differentiate the pluripotent embryonic stem cells to adipocytes. In this chapter, we describe a detailed protocol that is optimized for mouse embryonic stem cells. The result of this differentiation is a homogenous adipocyte monolayer culture that can be used for several applications including developmental and pharmacological research.

Study Question: Does a human fallopian tube (HFT) organoid model offer a favourable apical environment for human sperm survival and motility?
Summary Answer: After differentiation, the apical compartment of a new HFT organoid model provides a favourable environment for sperm motility, which is better than commercial media.
What Is Known Already: HFTs are the site of major events that are crucial for achieving an ongoing pregnancy, such as gamete survival and competence, fertilization steps, and preimplantation embryo development. In order to better understand the tubal physiology and tubal factors involved in these reproductive functions, and to improve still suboptimal in vitro conditions for gamete preparation and embryo culture during IVF, we sought to develop an HFT organoid model from isolated adult stem cells to allow spermatozoa co-culture in the apical compartment.

Article Synopsis
- Amniotic fluid contains stem cells (AF-SCs) that have potential uses in regenerative medicine for treating various injuries and diseases.
- When exposed to basic Fibroblast Growth Factor (bFGF), AF-SCs show the ability to survive and migrate in a rat brain model, resembling characteristics of neuronal/glial progenitor cells.
- The study employs electrophysiological techniques to identify specific potassium currents in AF-SCs and confirms that histamine can influence calcium dynamics and potassium current activation in these cells.

The nuclear matrix stabilizes primed-specific genes in human pluripotent stem cells.

The nuclear matrix, a proteinaceous gel composed of proteins and RNA, is an important nuclear structure that supports chromatin architecture, but its role in human pluripotent stem cells (hPSCs) has not been described. Here we show that by disrupting heterogeneous nuclear ribonucleoprotein U (HNRNPU) or the nuclear matrix protein, Matrin-3, primed hPSCs adopted features of the naive pluripotent state, including morphology and upregulation of naive-specific marker genes. We demonstrate that HNRNPU depletion leads to increased chromatin accessibility, reduced DNA contacts and increased nuclear size.

Replacing cells lost during the progression of neurodegenerative disorders holds potential as a therapeutic strategy. Unfortunately, the majority of cells die post-transplantation, which creates logistical and biological challenges for cell therapy approaches. The cause of cell death is likely to be multifactorial in nature but has previously been correlated with hypoxia in the graft core.
