The prevalence of type 2 diabetes (T2D) has increased significantly over the past three decades, with an estimated 30-40% of cases remaining undiagnosed. Brown and beige adipose tissues are known for their remarkable catabolic capacity, and their ability to diminish blood glucose plasma concentration. Beige adipose tissue can be differentiated from adipose-derived stem cells or through transdifferentiation from white adipocytes. However, the impact of T2D progression on beige adipocytes' functional capacity remains unclear. Transcriptomic profiling of subcutaneous adipose tissue biopsies from healthy normal-weight, obese, prediabetic obese, and obese subjects diagnosed with T2D, reveals a progressive alteration in cellular processes associated with catabolic metabolism, circadian rhythms, thermogenesis-related signaling pathways, cellular stress, and inflammation. MAX is a potential transcription factor that links inflammation with the circadian clock and thermogenesis during the progression of T2D. This study unveils an unrecognized transcriptional circuit that increasingly disrupts subcutaneous adipose tissue oxidative capacity during the progression of T2D. These findings could open new research venues for developing chrono-pharmaceutical strategies to treat and prevent T2D.

Ovarian cancer (OC) is characterized by high mortality rates due to late diagnosis, recurrence, and metastasis. Here, we show that extracellular signaling molecules secreted by adipose-derived mesenchymal stem cells (ASCs) and OC cells-either in the conditioned medium (CM) or within small extracellular vesicles (sEVs)-modulate cellular responses and drive OC progression. ASC-derived sEVs and CM secretome promoted OC cell colony formation, invasion, and migration while upregulating tumor-associated signaling pathways, including TGFβ/Smad, p38MAPK/ERK1/2, Wnt/β-catenin, and MMP-9.

Adipose-derived regenerative cells (ADRCs) are one of the most promising cell sources that possess significant therapeutic effects. They have now become a main source of cell therapy for the treatment of ischemic diseases due to their easy accessibility, expansion, and differentiation. Additionally, ADRCs can release multiple paracrine factors and extracellular vesicles that contribute to tissue regeneration by promoting angiogenesis, regulating inflammation, alleviating apoptosis, and inhibiting fibrosis.

Osteoarthritis (OA) is one of the most common degenerative diseases in dogs and humans, which can lead to articular cartilage deterioration, chronic pain, and decreased quality of life. The anti-inflammatory, anti-fibrotic, analgesic, and cartilage regeneration properties of mesenchymal stem cell (MSC) therapy provide a new direction for the treatment development of OA in the future. Currently, MSC therapy lacks confirmed ideal sources, dosages, formulations, and specific characteristics.

Different tissues have a normal color spectrum that reflects their cellular composition and/or metabolic features. Similarly, distinct color variations may occur in tissues that have undergone pathologic or nonpathologic changes. Common examples of color changes in domestic animal tissues include red (associated with erythrocytes, hemoglobin, and myoglobin), brown (ferric hemoglobin or myoglobin, suppurative inflammation, lipid oxidation, postmortem autolysis, formalin fixation, neoplasms arising from cytochrome-rich tissues), yellow (hemoglobin and iron degradation, biliary pigment and by-products, carotenes, keratin, necrosis, suppurative or fibrinous inflammation), green (hemoglobin and iron degradation, biliary pigment and by-products, meconium, eosinophilic or suppurative inflammation, oomycete and algal infections), white (lack of blood, adipose tissue and its neoplasms, chylous effusion, necrosis, mineralization, fibrosis, lymphoid tissue, round cell neoplasms), translucent (transudate, cysts), black to gray (hemoglobin and iron degradation, melanin, carbon, tattoos), and blue to purple (poorly oxygenated blood, tattoos).

Background: With the rising incidence of life expectancy, obesity, and tumours, understanding the incretory influence of adipose tissue in tumorigenesis becomes increasingly important. As the adipokines leptin and adiponectin are released by fat tissue, we aimed to analyse the expression of their respective receptors in tumours for which an association with obesity is epidemiologically hypothesised.
Methods: The expression of leptinR and adipoR1 were analysed in cohorts of renal cell cancer (n=391), cervical cancer (n=155), vulvar cancer (n=107), and endometrial cancer (n=90) by immunohistochemistry and correlated with clinicopathological parameters including survival times.
