  1. 6. Identifying and targeting vulnerabilities in cancers that metastasize to the bone and bone marrow

    Författare :Adele Mirna Alchahin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Evolving technologies enable scientist to ask and seek answers to advanced questions, above and beyond. During the past decade single-cell RNA sequencing (scRNA-seq) has revolutionized our understanding of biology, in particular within cancer research. LÄS MER

  3. 7. Development of Novel Models for Studying Osteoclasts

    Författare :Christian Thudium; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoclast; Osteopetrosis; Osteoporosis; Bone; Hematopoiesis; Gene Therapy; Mouse Models; oc oc; RANK KO;

    Sammanfattning : This thesis focuses on developing and characterizing novel models for studying osteoclasts with an emphasis on how mutations abolishing osteoclastic acidification affect osteoclast signaling and bone remodeling, as well as how to treat patients bearing these rare mutations. Bone remodeling is under normal circumstances a tightly balanced process where resorption of bone by osteoclasts is followed by adequate amounts of bone formation by osteoblasts. LÄS MER

  4. 8. Bone marrow mesenchymal stem and progenitor cells in myeloid malignancies

    Författare :Pingnan Xiao; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Hematopoietic stem cells (HSCs) reside in bone marrow (BM) microenvironment / niche to self-renew and generate all types of mature blood cells in postnatal life. This process is called hematopoiesis. Normal hematopoiesis is tightly regulated by both intrinsic signaling in HSCs and extrinsic signals from BM niche. LÄS MER

  5. 9. Understanding the role of bone marrow niche in myeloid malignancies

    Författare :Monika Dolinska; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Normal hematopoiesis is generated and maintained by rare hematopoietic stem cells (HSCs) through their capacity to self-renew and differentiate. This process is rigorously controlled, both by HSC-intrinsic molecular programs and extrinsic signals emitted by the local bone marrow (BM) microenvironment, the so-called HSC niche. LÄS MER

  7. 10. FLT3 receptor in normal and malignant hematopoiesis

    Författare :Shabnam Kharazi; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; FLT3-ITD; FLT3; lineage commitment; acute myeloid leukemia; myeloprolifetaive disease; hematopoietic stem cell;

    Sammanfattning : All hematopoietic cells originate from hematopoietic stem cells (HSCs) residing in the bone marrow (BM). The classical model of hematopoietic lineage commitment, that has been the prevailing model for hematopoiesis, proposes that the first lineage commitment step of HSCs and progenitors results in a strict separation of myelopoiesis and lymphopoiesis.
