Differentiatie van door de mens geïnduceerde pluripotente stamcellen

3D-cultuurmodellen als drugtestplatforms bij hondenlymfoom en hun overspraak met lymfeklier-afgeleide stromacellen

Background: Malignant lymphoma is the most common hematopoietic malignancy in dogs, and relapse is frequently seen despite aggressive initial treatment. In order for the treatment of these recurrent lymphomas in dogs to be effective, it is important to choose a personalized and sensitive anticancer agent. To provide a reliable tool for drug development and for personalized cancer therapy, it is critical to maintain key characteristics of the original tumor.
Objectives: In this study, we established a model of hybrid tumor/stromal spheroids and investigated the association between canine lymphoma cell line (GL-1) and canine lymph node (LN)-derived stromal cells (SCs).
Methods: A hybrid spheroid model consisting of GL-1 cells and LN-derived SC was created using ultra low attachment plate. The relationship between SCs and tumor cells (TCs) was investigated using a coculture system.
Results: TCs cocultured with SCs were found to have significantly upregulated multidrug resistance genes, such as P-qpMRP1, and BCRP, compared with TC monocultures. Additionally, it was revealed that coculture with SCs reduced doxorubicin-induced apoptosis and G2/M cell cycle arrest of GL-1 cells.
Conclusions: SCs upregulated multidrug resistance genes in TCs and influenced apoptosis and the cell cycle of TCs in the presence of anticancer drugs. This study revealed that understanding the interaction between the tumor microenvironment and TCs is essential in designing experimental approaches to personalized medicine and to predict the effect of drugs.
Keywords: Canine lymphoma; drug resistance; lymph node-derived stromal cell; personalized cancer therapy; tumor microenvironment.

Het overwinnen van kweekbeperking voor SARS-CoV-2 in menselijke cellen vergemakkelijkt het screenen van verbindingen die virale replicatie remmen

Efforts to mitigate the COVID-19 pandemic include screening of existing antiviral molecules that could be re-purposed to treat SARS-CoV-2 infections. Although SARS-CoV-2 replicates and propagates efficiently in African green monkey kidney (Vero) cells, antivirals such as nucleos(t)ide analogs (nucs) often show decreased activity in these cells due to inefficient metabolization. SARS-CoV-2 exhibits low viability in human cells in culture.
Here, serial passages of a SARS-CoV-2 isolate (original-SARS2) in the human hepatoma cell clone Huh7.5 led to the selection of a variant (adapted-SARS2) with significantly improved infectivity in human liver (Huh7 and Huh7.5) and lung cancer cells (unmodified Calu-1 and A549). The adapted virus exhibited mutations in the spike protein, including a 9 amino acid deletion and 3 amino acid changes (E484D, P812R, and Q954H). E484D also emerged in Vero E6 cultured viruses that became viable in A549 cells.
Original and adapted viruses were susceptible to SR-B1 receptor blocking and adapted-SARS2 exhibited significantly less dependency of ACE2. Both variants were similarly neutralized by COVID-19 convalescent plasma but adapted-SARS2 exhibited increased susceptibility to exogenous type I interferon. Remdesivir inhibited original- and adapted-SARS2 similarly, demonstrating the utility of the system for the screening of nucs.
Among the tested nucs, only remdesivir, molnupiravir and to a limited extent galidesivir, showed antiviral effect across human cell lines, whereas sofosbuvir, ribavirin, and favipiravir had no apparent activity. Analogously to the emergence of spike mutations in vivo, the spike protein is under intense adaptive selection pressure in cell culture. Our results indicate that the emergence of spike mutations will most likely not affect the activity of remdesivir.

EUR 206.18
Description: N-RAS Antibody: Activating mutations and overexpression of classical Ras subfamily members (N-RAS, H-RAS, and K-RAS) have been widely investigated as key events in the development of human cancers. The N-RAS protein shuttles between the Golgi apparatus and the plasma membrane. This shuttling is regulated through palmitoylation and depalmitoylation by the ZDHHC9-GOLGA7 complex. N-RAS, which has intrinsic GTPase activity, is activated by a guanine nucleotide-exchange factor and inactivated by a GTPase activating protein. Mutations in this gene have been associated with somatic rectal cancer, follicular thyroid cancer, autoimmune lymphoproliferative syndrome, Noonan syndrome, and juvenile myelomonocytic leukemia.

KappaB ras Antibody

2491-002mg 0.02 mg
EUR 206.18
Description: KappaB ras Antibody: KappaB ras-1 (κB-ras-1) and kappaB-ras-2 are two small proteins that similar to Ras-like small GTPases that associate with IκB (IκB), an inhibitor of the transcription factor NF-κB. IκB exists in two homologous forms, IκB-alpha and IκB-beta, although IκB-beta contains a unique 47-amino acid region within its ankyrin domain. While inactive IκB-alpha-NF-κB complexes can shuttle in and out of the nucleus, IκB-beta-NF-κB complexes are retained exclusively in the cytoplasm. It is suggested that kappaB-ras proteins preferentially bind to the IκB-beta form through this unique insert within the ankyrin region, thus modulating the cellular location of IκB-beta and regulating the rate of degradation of IκB-beta. This antibody detects both kappaB-ras1 and kappaB-ras2.

In vitro differentiatie van menselijke pluripotente stamcellen in de B-lijn met behulp van OP9-MS5 co-cultuur

 

In vitro differentiation of human pluripotent stem cells (hPSCs) offers a genetically tractable system to examine the physiology and pathology of human tissue development and differentiation. We have used this approach to model the earliest stages of human B lineage development and characterize potential target cells for the in utero initiation of childhood B acute lymphoblastic leukemia.
Herein, we detail critical aspects of the protocol including reagent validation, controls, and examples of surface markers used for analysis and cell sorting. For complete details on the use and execution of this protocol, please refer to Boiers et al. (2018).

Differentiatie van door de mens geïnduceerde pluripotente stamcellen tot definitief endoderm met behulp van een eenvoudig dialysecultuurapparaat

Therapeutic use of differentiated organ cells from human induced pluripotent stem cells (hiPSCs) is one of the promising strategies for regenerative medicine. Differentiation into definitive endoderm is an essential process in the preparation of metabolic organs. However, the manufacturability of differentiation is limited due to the high-cost cytokines required for the differentiation of endodermal lineage.
Furthermore, the cytokines remaining in the used culture medium and possible endogenous factors are removed along with toxic metabolites by the medium replacement. To address these problems, the application of dialysis culture can retain and fully utilize their accumulation to create a better culture environment that contributes to differentiation cost reduction.
The control of glycosylation profiles is essential to the consistent manufacture of therapeutic monoclonal antibodies that may be produced from a variety of cell lines including CHO and NS0. Of particular concern is the potential for generating non-human epitopes such as N-glycolylneuraminic acid (Neu5Gc) and Galα1-3 Gal that may be immunogenic. We have looked at the effects of a commonly used media supplements of manganese, galactose and uridine (MGU) on Mab production from CHO and NS0 cells in enhancing galactosylation and sialylation as well as the generation of these non-human glycan epitopes.
In the absence of the MGU supplement, the humanized IgG1 antibody (Hu1D10) produced from NS0 cells showed a low level of mono- and disialylated structures (SI:0.09) of which 75% of sialic acid was Neu5Gc. The chimeric human-llama Mab (EG2-hFc) produced from CHO cells showed an equally low level of sialylation (SI: 0.12) but the Neu5Gc content of sialic acid was negligible (<3%). Combinations of the MGU supplements added to the production cultures resulted in a substantial increase in the galactosylation of both Mabs (up to GI:0.78 in Hu1D10 and 0.81 in EG2-hFc).
However, the effects on sialylation differed between the two Mabs. We observed a slight increase in sialylation of the EG2-hFc Mab by a combination of MG but it appeared that one of the components (uridine) was inhibitory to sialylation.
On the other hand, MG or MGU increased sialylation of Hu1D10 substantially (SI:0.72) with an increase that could be attributed predominantly to the formation of Neu5Ac rather than Neu5Gc. The increased level of galactosylation observed with MG or MGU was attributed to an activation of the galactosyl transferase enzymes through enhanced intracellular levels of UDP-Gal and the availability of Mn2+ as an enzymic co-factor.
However, this effect not only increased the desirable beta 1-4 Gal linkage to GlcNAc but unfortunately in NS0 cells increased the formation of Galα1-3 Gal which was shown to increase x3 in the presence of combinations of the MGU supplements. Supplementation of media with fetal bovine serum (FBS) increased the availability of free Neu5Ac which resulted in a significant increase in the sialylation of Hu1D10 from NS0 cells. This also resulted in a significant decrease in the proportion of Neu5Gc in the measured sialic acid from the Mab.
