To achieve that, the exosomes were preconcentrated from cell-culture supernatant (and eventually in human serum) on magnetic particles modified with antibodies against the general tetraspanins CD9, CD63 and CD81, as well as specific receptors of cancer (CD24, CD44, CD54, CD326 and CD340).
Furthermore, high CPA4 expression in TNBC cases was associated with low expression of E‑cadherin and with the expression of cancer stem cell markers (high CD44/low CD24).
Importantly, shNEAT1 reduced stem cell populations such as CD44+/CD24-, ALDH+, and SOX2+, implicating that NEAT1 was closely related to cancer stemness in TNBC.
Stimulation with SHH resulted in an up-regulation of cancer stemness in EC sphere cultures, as indicated by increased sphere formation after sorting for CD44+/CD24- EC cancer stem-like cell (CSC) population.
AI-resistant cell lines expressing ER (Type 1 V1 and V2) showed high cancer stemness in terms of their CD44/CD24 expression and side populations, which were stimulated by the addition of estrogen and inhibited by fulvestrant.
Corrigendum to "Expression and Clinical Significance of Cancer Stem Cell Markers CD24, CD44, and CD133 in Pancreatic Ductal Adenocarcinoma and Chronic Pancreatitis".
Knockdown of TRIB3 in radioresistant MDA-MB-231 TNBC cells decreased Notch1 activation, as well as the CD24-CD44⁺ cancer stem cell population, and sensitized cells toward radiation treatment.
mtDNA depletion triggers chemoresistance in cancer cell lines and is correlated with increase and decrease of CD44 and CD24 positivity respectively in HGC-27 and MKN-45 GC cell lines.
CD24 (cluster of differentiation 24) is a small heavy glycosylated protein, which is overexpressed in many cancer and some cancer stem cells and is associated with the development, invasion, and metastasis of cancer cells.
Flow cytometry confirmed an elevated percentage of cells carrying cancer stem cells (CSCs) markers (CD44<sup>+</sup>/CD24<sup>-</sup>) in the reversed breast cancer cell population, with hypomethylated CD44 promoters and hypermethylated CD24 promoters.
To assess the expression of cancer stem cell (CSC) markers CD44, CD133 and CD24 in colon cancer liver metastases and analyse their predictive value for overall survival (OS) and disease-free survival (DFS) after liver resection.
Tumor growth parameters were analyzed together with histopathological examination and immunohistochemical detection of KI67 (proliferation marker), caspase-3, BAX, BCL-2 (apoptosis markers), and CD24 and CD44 (cancer stem cell markers) in mammary tumor samples.
Detailed topographic analyses, with immunohistochemical staining for β-catenin and cancer stem cell (CSC) markers (CD44, CD24, and CD166) were performed.
