cell pictures anywhere?

[Guest guest]

We just got our Frys lab pictures. Did someone post some good cell pictures a

while back: spikey and doghnut shapes are what we got. If anyone knows any

reference pictures or -or geeees - treatments? . . . let me know.

Thanks,

spikey shapes are just a result of the blood preparation, e.g. type of slide

cover glass, pressure applied, aging of the sample etc. The donut shape is

normal, when it ages or in certain conditions the rbc starts to contract and you

see spikes caused by the internal cell skeleton structure. This process is

called crenation.

You can't draw any conclusions from such pictures unless you know exactly how

the sample was treated etc. If there are parasites visible (either internal or

external, e.g. small dots attached to the rbc's) the lab would probably indicate

that.

For some info about rbc shapes check this wiki article plus the pictures, or

search for 'red blood cell crenation'.

there are many resources online for studying blood cell shapes; it's all very

confusing to say the least ...
