This protocol details the derivation of transplantable hematopoietic stem cells from mouse embryonic stem cells (ESC) and their subsequent injection into lethally irradiated recipient mice. Briefly, ESC are differentiated as embryoid bodies, which are then infected with retroviral HoxB4 and co-cultured with OP9 stromal cells and hematopoietic cytokines.

Metaphase to anaphase transition is triggered through anaphase-promoting complex (APC/C)-dependent ubiquitination and subsequent destruction of cyclin B. Here, we established a system which, following pulse-chase labeling, allows monitoring cyclin B proteolysis in entire cell populations and facilitates the detection of interference by the mitotic checkpoint.
FAQs
The light-dependent reactions capture light energy and generate ATP and NADPH inside chloroplasts. These energy carriers then support the Calvin cycle, which fixes carbon dioxide into sugars. This division of roles links light capture with carbon fixation and explains how mesophyll activity contributes to overall plant productivity.
Palisade mesophyll cells are specialized for efficient light capture, whereas spongy mesophyll cells contain air spaces that support carbon dioxide and oxygen diffusion. Their contrasting structures allow different aspects of photosynthesis and gas exchange to occur effectively within the same leaf, contributing to coordinated leaf function.
ATP and NADPH carry the energy and reducing power produced during the light-dependent reactions into the Calvin cycle. There, they support the fixation of carbon dioxide into sugars. Examining this connection clarifies why chloroplast activity is essential for converting absorbed light energy into stored chemical energy.
Air spaces within spongy mesophyll provide internal pathways that support the diffusion of carbon dioxide and oxygen. This arrangement helps carbon dioxide reach photosynthetic cells while allowing oxygen to move through the leaf. Consequently, spongy mesophyll structure is closely connected to efficient gas exchange during photosynthetic activity.
Mesophyll cells provide a cellular basis for examining plant productivity because their chloroplasts carry out light reactions and carbon fixation. Comparing their photosynthetic roles can help relate leaf function to the amount of chemical energy and sugar produced, offering context for differences in plant growth and crop performance.
Their organization links light capture, carbon fixation, and gas diffusion, making mesophyll cells useful for studying how leaves function under differing environmental conditions. Investigations can focus on palisade specialization, spongy air spaces, or photosynthetic reactions to connect cellular features with leaf adaptation, stress responses, and crop performance.
