Into the Deepbone

Human bone marrow mesenchymal stem cells (HMSC) can differentiate into any of the many bone marrow-derived cells (except the red and white blood cells) and are of great interest to researchers in many biomedical fields, including tissue regeneration, cancer and stem cell therapies. Now, thanks to a new bone tissue clearing approach called DeepBone, they can be studied and mapped in 3D within their natural bone marrow environment (components of which can also be characterised) – this study compares HMSC in the marrow of the young and aged

Clear Headed

Biologists usually have a 'bucket list' – details they want to know, hidden in delicate processes too fast or life-threatening to observe, or structures too small to see at all. Microscopy usually requires a compromise between the big picture and looking in detail. Here a new type of light sheet microscopy, called ExA-SPIM, allows scientists to see in high resolution over a wide area in a mouse’s brain. Zooming through the brain, we can see spindly neurons stretching out. The clarity of the image is thanks in part to techniques to first clear away opaque chemicals like fats, then to ‘expand’ the brain tissue – swelling it with salty liquid so its structures are easier to image. Fusing together multiple large image 'tiles' like this one allows the scientists to follow neurons running in all directions through the brain tissue, giving them a clearer picture of the connections inside.

Cleared to Attack

Using techniques such as single-cell RNA sequencing and high-resolution imaging with tissue clearing, this study in mice identifies a nerve subset called vagal sensory neurons (shown in magenta in this cleared mouse heart) that increase ventricular innervation in the heart after a heart attack (myocardial infarction). These neurons are revealed as part of a heart-brain neuroimmune loop that presents possible targets for MI therapies

Nervous Revelations

Tissue samples from biopsies or post-mortem can be stored long-term by 'fixing' in formalin but this treatment ruins the potential for many kinds of subsequent analyses. Here, visualising neurons and their circuitry in fixed brain samples is made possible using a tissue clearing and molecular labelling techniques
