Adipose tissue is composed of anatomically distinct depots that mediate several important aspects of energy homeostasis. The past two decades have witnessed increased research effort to elucidate the ontogenetic basis of adipose form and function. In this Review, we discuss advances in our understanding of adipose tissue development with particular emphasis on the embryonic patterning of depot-specific adipocyte lineages and adipocyte differentiation Micro-environmental cues and other factors that influence cell identity and cell behavior at various junctures in the adipocyte lineage hierarchy are also considered.

Despite being a major target of reconstructive surgery, development of the ear pinna remains poorly studied. Here we provide a cellular characterization of late gestational and postnatal ear pinna development in two rodents and investigate the role of BMP5 in expansion and differentiation of auricular elastic cartilage. We find that ear pinna development is largely conserved between Mus musculus and the highly regenerative Acomys dimidiatus.

Introduction: Bone aging is linked to changes in the lineage differentiation of bone marrow stem cells (BMSCs), which show a heightened tendency to differentiate into adipocytes instead of osteoblasts. The therapeutic potential of irisin in addressing age-related diseases has garnered significant attention. More significantly, irisin has the capacity to enhance bone mass recovery and sustain overall bone health.

Purpose Of Review: Bone marrow adipose tissue is a distinctive fat depot located within the skeleton, with the potential to influence both local and systemic metabolic processes. Although significant strides have been made in understanding bone marrow adipose tissue over the past decade, many questions remain regarding their precise lineage and functional roles.
Recent Findings: Recent studies have highlighted bone marrow adipose tissue's involvement in continuous cross-talk with other organs and systems, exerting both endocrine and paracrine functions that play a crucial role in metabolic homeostasis, skeletal remodeling, hematopoiesis, and the progression of bone metastases.

Mesenchymal stromal cells (MSCs) have the potential for novel treatments of several musculoskeletal conditions due to their ability to differentiate into several cell lineages including chondrocytes, adipocytes and osteocytes. Researchers are exploring whether this could be utilized for novel therapies for joint afflictions. The role of gender in the ability of MSCs to differentiate and proliferate into different cells has not been clearly defined.

In obesity, C-C chemokine ligand 2 (CCL2) plays a critical role in recruiting macrophages to white adipose tissue (WAT), contributing to chronic inflammation. In this study, we sought to explore the effects of fish oil (FO) on CCL2 expression and histone (H3K27)-modifying enzymes in both human model of preadipocytes and primary adipose-derived stem cells (ASCs). Present findings in preadipocytes lineage evidenced that lipopolysaccharide (LPS) increased (∼5.
