Do we freeze those left-over cells? π€βοΈ Yes or no? π€π€

After an experiment we often end up with left-over cells. They are also not needed for further cultivation as you have already routinely seeded an aliquot. So, what do you do with left-over cells?
Trash them? Really?? But, but, butβ¦!! π³π³π³
Or, freeze them, to save the poor cells from the tragic fate of being trashed and autoclaved?
Well, here is why it might not be a good idea to freeze them.

Hey, can I have a spot in your laminar hood? π€

βI just need to do a quick medium change. Donβt worry, I wonβt need much space!β ππ
What would you do in this situation? Exactly. Say no. βπ
But can it harm to share the hood with someone else for a short time π? Yes, it can. π«΅
There is an increased risk of cross-contamination πππ, the worst type of contamination in the cell culture lab.
This can happen through
π Aerosol formation while working. Remember, even the best pipetting practices will generate at least small amounts of aerosols.

Biodiversity at our workplaces ππ¦£π¦

It is common knowledge that the greater the biological diversity of an #ecosystem, the higher its likelihood to survive. Why? Well, because ecosystems with more options to respond to external or internal challenges simply have bigger potential for #adaptation. πͺπͺ
Time and time again, we have seen that diversity is also important for the composition of teams in life science labs. Here, we are not talking just about the diversity regarding gender, nationality, age etc. We take this for [β¦]
Can we, the Cell Culture People, learn from Project Management? π

Yes, we can. Here is why. π
A project is βa piece of planned work or an activity that is finished over a period of time and intended to achieve a particular purposeβ according to #CambridgeDictionary. ππ
Well, they could be talking about experiments, right? π
After all, an experiment has to be
β planned π
β executed π―
β and finished within a certain period of time. π
But there is more to it. β
In project management it is said that β1 [β¦]
Spring Equinox – π· The beautiful connection between astronomy and cell biology π·

Melting snow, blooming flowers, sprouting greenery caused by the tilt of the earthβs axis. The sunβs rays hit the northern hemisphere at a steeper angle βπ, resulting in longer daylight, warmer temperatures, buzzing insects π¦, hungry bees π and chirping birds π¦. Reproductive systems awaken π, as more food is available the following months, ensuring better survival of offspring π£π₯.
The earth moves around the sun at a speed of 30 km/s and with an inclined axis. This [β¦]
The Fabric of New Ideas and Inspiring Collaborations: π The Austrian Cluster for Tissue Regeneration Meeting 2025 π

The 19th Annual Meeting of the Austrian Cluster for Tissue Regeneration 2025 took place in the 200-year-old domed hall of the Technical University Vienna (β#Kuppelsaalβ) with its impressive wooden construction with exposed arched trusses by de LβOrme. ποΈ
